Transplantation of human umbilical cord blood mononuclear cells promotes functional endometrium reconstruction via downregulating EMT in damaged endometrium. Regen Ther 2024; 27:279-289. [PMID: 38617444 PMCID: PMC11010781 DOI: 10.1016/j.reth.2024.03.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/06/2024] [Accepted: 03/28/2024] [Indexed: 04/16/2024] Open
Abstract
Introduction Cell transplantation is an emerging and effective therapeutic approach for enhancing uterine adhesions caused by endometrial damage. Currently, human umbilical cord blood mononuclear cells (HUCBMCs) have been extensively for tissue and organ regeneration. However, their application in endometrial repair remains unexplored. Our investigation focuses on the utilization of HUCBMCs for treating endometrial injury. Methods The HUCBMCs were isolated from health umbilical cord blood, and co-cultured with the injured endometrial stromal cells and injured endometrial organoids. The cell proliferation and apoptosis were measured by cck8 assays and flow cytometry. Western blotting was used to detect the expression of PTEN, AKT and p-AKT. Immunofluorescence assay revealed expression levels of epithelial-mesenchymal transition (EMT) -related markers such as E-cadherin, N-cadherin, and TGF-β1. The endometrial thickness, fibrosis level, and glandular number were examined after the intravenous injection of HUCBMCs in mouse endometrial models. Immunohistochemistry was employed to assess changes in growth factors vascular endothelial growth factor (VEGF) and insulin-like growth factor 1 (IGF-1) as well as fibrosis markers α-SMA and COL1A1. Additionally, expressions of EMT-related proteins E-cadherin and N-cadherin were evaluated. Results HUCBMCs significantly improved the proliferation and reduced the apoptosis of damaged endometrial stromal cells (ESCs), accompanied by up-regulation of phospho-AKT expression. HUCBMCs increased endometrial thickness and glandular count while decreasing fibrosis and EMT-related markers in mouse endometrial models. Furthermore, EMT-related markers of ESCs and endometrial organoids were significantly decreased. Conclusions Our findings suggest that HUCBMCs plays a pivotal role in mitigating endometrial injury through the attenuation of fibrosis. HUCBMCs may exert a reverse effect on the EMT process during the endometrium reconstruction.

Abstract
A single injection of platelet-rich plasma (PRP) or stromal vascular fraction (SVF) in treating neurological ailments suggests promise; however, there is limited evidence of the efficacy of combination therapy. This trial aimed to determine whether combining SVF and PRP could provide further therapeutic effects in treating multiple sclerosis (MS). Fifteen Persian cats were separated into three groups (n = 5): group I (control negative), and group II (control positive); EB was injected intrathecally into the spinal cord and then treated 14 days later with intrathecal phosphate buffered saline injection, and group III (SVF + PRP), cats were injected intrathecally with EB through the spinal cord, followed by a combination of SVF and PRP 14 days after induction. Therapeutic effects were evaluated using the Basso-Beattie-Bresnahan scale throughout the treatment timeline and at the end. Together with morphological, MRI scan, immunohistochemical, transmission electron microscopy, and gene expression investigations. The results demonstrated that combining SVF and PRP successfully reduced lesion intensity on gross inspection and MRI. In addition to increased immunoreactivity to Olig2 and MBP and decreased immunoreactivity to Bax and GFAP, there was a significant improvement in BBB scores and an increase in neurotrophic factor (BDNF, NGF, and SDF) expression when compared to the positive control group. Finally, intrathecal SVF + PRP is the most promising and safe therapy for multiple sclerosis, resulting in clinical advantages such as functional recovery, MRI enhancement, and axonal remyelination.

Abstract
Spinal cord injury (SCI) is a nervous system disease characterized by sensory and motor dysfunction, axonal apoptosis, decreased vascular density, and inflammation. At present, surgical treatment, drug treatment, and cell therapy can be used. Surgical treatment can improve motor and independent function scores, and drug treatment can promote the recovery of neurons in the spinal cord, but only improve symptoms. Complete recovery of SCI has not yet been achieved. However, the differentiation of stem cells brings hope for the treatment of SCI. Umbilical cord blood cells (UCBs) are ethically readily available and can repair neuronal damage. However, it is still unclear how they can improve symptoms and repair nerve severity. In this paper, the role of UCBs in the treatment of SCI is described in detail from different aspects such as behavior, morphology, and molecular expression changes, so as to provide new ideas and theoretical directions for future research.

Abstract
BACKGROUND: Stroke is the second most cause of death in the world. There are several treatments but they often end up with disabilities. Recently, cell therapy has become a new hope as an alternative treatment as it could improve the patients neurological deficits and daily living activities. Cord blood mononuclear cells (CB-MNCs) are one of the cell therapies for post-ischemic neurogenesis by intravenous or intra-arterial administration; however, it is not clear which one is better.
AIM: This study aims to compare the effects of intra-arterial and intravenous administration of human CB-MNC on cortical neurogenesis of rat brain after ischemic stroke.
METHODS: Twenty-four rats were divided into four groups, that is, control, middle cerebral artery obstruction (MCAO) without treatment, MCAO with intra-arterial CB-MNC injection (MCAO-IA), and MCAO with intravenous CB-MNC injection (MCAO-IV). Two weeks after injection, all rats were sacrificed, the brain was harvested, histologically process and stained with hematoxylin eosin (HE) to determine cellular and tissue morphology changes, and immunohistochemical staining, anti-NeuN antibody to determine the number of cortical neurons. The HE showed that MCAO rat brain had gliosis and shrunken cells.
RESULTS: The results showed that MCAO-IA and MCAO-IV had fewer areas of gliosis and shrunken cells when compared to the MCAO group. The number of neurons also showed an increase. However, there was no difference between the MCAO-IA and MCAO-IV groups. It was concluded both of them could improve neurogenesis.
CONCLUSION: CB-MNC administration can be an alternative for stroke ischemic therapy because it is proven to increase neurogenesis and reduce gliosis areas. However, there was no difference in neurogenesis in the brain tissue of mice injected with CB-MNC intravenously or intra-arterially.

Abstract
Umbilical cord blood transplantation was first reported in 1980. Since then, additional research has indicated that umbilical cord blood stem cells (UCBSCs) have various advantages, such as multi-lineage differentiation potential and potent renewal activity, which may be induced to promote their differentiation into a variety of seed cells for tissue engineering and the treatment of clinical and metabolic diseases. Recent studies suggested that UCBSCs are able to differentiate into nerve cells, chondrocytes, hepatocyte-like cells, fat cells and osteoblasts. The culture of UCBSCs has developed from feeder-layer to feeder-free culture systems. The classical techniques of cell labeling and tracing by gene transfection and fluorescent dye and nucleic acid analogs have evolved to DNA barcode technology mediated by transposon/retrovirus, cyclization recombination-recombinase and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 strategies. DNA barcoding for cell development tracing has advanced to include single cells and single nucleic acid mutations. In the present study, the latest research findings on the development and differentiation, culture techniques and labeling and tracing of UCBSCs are reviewed. The present study may increase the current understanding of UCBSC biology and its clinical applications.

Abstract
Human dental pulp stem cells (hDPSCs) are promising source of cells for numerous and varied regenerative medicine applications as those possess high proliferation potential with multilineage differentiation capacity compare to other sources of adult stem cells; therefore, hDPSCs could be the good source for autologous transplantation in tissue engineering and regenerative medicine. In this study stem cells were isolated from dental pulp and were characterised by flowcytometry and immunocytochemistry. The controlled cells as well as, 7-day cultured cells were positive for transcription factors, OCT 4 and SOX 2 thatconfirmed isolated cellsasmesenchymal stem cells (MSCs). These cells showed positive expression for CD 19, CD 73, CD 90, CD 105 and are negative for CD 34, CD 45. Viability of hDPSCS were studied by trypan blue (TB) staining and fluorescent microscopic study. After 7 days of passaging by using several growth factors, cells express neural cell markers oligodendrocyte and glial fibrillary acidic protein. Specifically, osteocytes were grown from dental pulp MSCSsin vitro with the help of growth factors, dexamethasone, ascorbic acid-2- phosphate and β-glycerophosphate whereas, adipocytes were grown with indomethacin, 3-isobutyl-1-methylxanthine and insulin. Osteocytes and adipocytes were characterized by von Kossa and Oil red O staining, respectively. Chromosomal analysis of dental pulp-MSCs was done for qualitative assessment of MSCs. Karyotyping indicated diploid chromosome number in dental pulp derived MSCs. In vitro grown osteocytes could be used for bone fracture reunion cases, and adipocytes could be used for further research purposes.

Abstract
Peripheral nerve injury is an important cause of incapability and has limited available treatment. Autologous donor nerve implant is the golden standard treatment, however, may cause secondary deficits. Stem cells show positive results in preclinical settings, preserving tissue and function. We tested the efficacy of stem cells derived from human exfoliated deciduous teeth seeded in poly (lactide-co-glycolide) scaffolds in sciatic nerve transection model. Seventy-two adult male Wistar rats had 7-mm nerve gap bridge using scaffolds with (or without) stem cells. Animals were randomly divided into: sham-operated; sham-operated without scaffold; sham-operated + scaffold + stem cells; sciatic transection + no treatment; sciatic transection + acellular scaffolds; sciatic transection + scaffold + stem cells. Sciatic Functional Index and Ladder Rung Walking tests were performed before (-1), 14 and 28 days after surgery. Morphometric nerve measurement and muscle weights were assessed. Scaffolds with stem cells improved function in Sciatic Functional Index. Acellular scaffold was effective, promoting functional recovery and nerve regeneration following nerve injury. Scaffolds provide better nerve regeneration and functional recovery after sciatic transection. Despite cell therapy promoting faster recovery after sciatic transection in the Sciatic Index Score, stem cells did not improve functional and morphological recovery after nerve injury. This is the first study testing the potential use of scaffolds combined with stem cells in the early stages after injury. Scaffolds with stem cells could accelerate nerve recovery and favor adjuvant therapies, evidencing the need for further studies to increase the knowledge about stem cells' mechanisms.

Abstract
The transplantation of stem cells from human exfoliated deciduous teeth (SHED) has been studied as a possible treatment strategy for spinal cord injuries (SCIs) due to its potential for promoting tissue protection and functional recovery. The aim of the present study was to investigate the effects of the early transplantation of SHED on glial scar formation and astrocytic reaction after an experimental model of SCI. Wistar rats were spinalized using the NYU Impactor. Animals were randomly distributed into three groups: control (naive) (animal with no manipulation); SCI (receiving laminectomy followed by SCI and treated with vehicle), and SHED (SCI rat treated with intraspinal SHED transplantation, 1 h after SCI). In vitro investigation demonstrated that SHED were able to express mesenchymal stem cells, vimentin and S100B markers, related with neural progenitor and glial cells, respectively. The acute SHED transplantation promoted functional recovery, measured as from the first week after spinal cord contusion by Basso, Beattie, and Bresnahan scale. Twenty-four and 48 h after lesion, flow cytometry revealed a spinal cord vimentin+ cells increment in the SHED group. The increase of vimentin+ cells was confirmed by immunofluorescence. Moreover, the bioavailability of astrocytic proteins such as S100B and Kir4.1 shown to be increased in the spinal cord of SHED group, whereas there was a glial scar reduction, as indicated by ELISA and Western blot techniques. The presented results support that SHED act as a neuroprotector agent after transplantation, probably through paracrine signaling to reduce glial scar formation, inducing tissue plasticity and functional recovery.

Abstract
Umbilical cord blood-derived mononuclear cell (UCB-MNC) transplants improve recovery in animal spinal cord injury (SCI) models. We transplanted UCB-MNCs into 28 patients with chronic complete SCI in Hong Kong (HK) and Kunming (KM). Stemcyte Inc. donated UCB-MNCs isolated from human leukocyte antigen (HLA ≥4:6)-matched UCB units. In HK, four patients received four 4-μl injections (1.6 million cells) into dorsal entry zones above and below the injury site, and another four received 8-μl injections (3.2 million cells). The eight patients were an average of 13 years after C5-T10 SCI. Magnetic resonance diffusion tensor imaging of five patients showed white matter gaps at the injury site before treatment. Two patients had fiber bundles growing across the injury site by 12 months, and the rest had narrower white matter gaps. Motor, walking index of SCI (WISCI), and spinal cord independence measure (SCIM) scores did not change. In KM, five groups of four patients received four 4-μl (1.6 million cells), 8-μl (3.2 million cells), 16-μl injections (6.4 million cells), 6.4 million cells plus 30 mg/kg methylprednisolone (MP), or 6.4 million cells plus MP and a 6-week course of oral lithium carbonate (750 mg/day). KM patients averaged 7 years after C3-T11 SCI and received 3-6 months of intensive locomotor training. Before surgery, only two patients walked 10 m with assistance and did not need assistance for bladder or bowel management before surgery. The rest could not walk or do their bladder and bowel management without assistance. At about a year (41-87 weeks), WISCI and SCIM scores improved: 15/20 patients walked 10 m ( p = 0.001) and 12/20 did not need assistance for bladder management ( p = 0.001) or bowel management ( p = 0.002). Five patients converted from complete to incomplete (two sensory, three motor; p = 0.038) SCI. We conclude that UCB-MNC transplants and locomotor training improved WISCI and SCIM scores. We propose further clinical trials.

Human dental pulp stem cells transplantation combined with treadmill training in rats after traumatic spinal cord injury. ACTA ACUST UNITED AC 2017; 49:e5319. [PMID: 27509306 PMCID: PMC4988478 DOI: 10.1590/1414-431x20165319] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Accepted: 06/13/2016] [Indexed: 01/09/2023]
Abstract
Spinal cord injury (SCI) is a disabling condition resulting in deficits of sensory and motor functions, and has no effective treatment. Considering that protocols with stem cell transplantation and treadmill training have shown promising results, the present study evaluated the effectiveness of stem cells from human exfoliated deciduous teeth (SHEDs) transplantation combined with treadmill training in rats with experimental spinal cord injury. Fifty-four Wistar rats were spinalized using NYU impactor. The rats were randomly distributed into 5 groups: Sham (laminectomy with no SCI, n=10); SCI (laminectomy followed by SCI, n=12); SHEDs (SCI treated with SHEDs, n=11); TT (SCI treated with treadmill training, n=11); SHEDs+TT (SCI treated with SHEDs and treadmill training; n=10). Treatment with SHEDs alone or in combination with treadmill training promoted functional recovery, reaching scores of 15 and 14, respectively, in the BBB scale, being different from the SCI group, which reached 11. SHEDs treatment was able to reduce the cystic cavity area and glial scar, increase neurofilament. Treadmill training alone had no functional effectiveness or tissue effects. In a second experiment, the SHEDs transplantation reduced the TNF-α levels in the cord tissue measured 6 h after the injury. Contrary to our hypothesis, treadmill training either alone or in combination, caused no functional improvement. However, SHEDs showed to be neuroprotective, by the reduction of TNF-α levels, the cystic cavity and the glial scar associated with the improvement of motor function after SCI. These results provide evidence that grafted SHEDs might be an effective therapy to spinal cord lesions, with possible anti-inflammatory action.

Neuroprotector effect of stem cells from human exfoliated deciduous teeth transplanted after traumatic spinal cord injury involves inhibition of early neuronal apoptosis. Brain Res 2017; 1663:95-105.

Abstract
Stem cells from human exfoliated deciduous teeth (SHED) transplants have been investigated as a possible treatment strategy for spinal cord injuries (SCI) due to their potential for promoting functional recovery. The aim of present study was to investigate the effects of SHED on neuronal death after an experimental model of SCI. METHODS Wistar rats were spinalized using NYU impactor®. Animals were randomly distributed into 4 groups: Control (Naive) or Surgical control, Sham (laminectomy with no SCI); SCI (laminectomy followed by SCI, treated with vehicle); SHED (SCI treated with intraspinal transplantation of 3×105 SHED, 1h after SCI). Functional evaluations and morphological analysis were performed to confirm the spinal injury and the benefit of SHED transplantation on behavior, tissue protection and motor neuron survival. Flow cytometry of neurons, astrocytes, macrophages/microglia and T cells of spinal cord tissue were run at six, twenty-four, forty-eight and seventy-two hours after lesion. Six hours after SCI, ELISA and Western Blot were run to assess pro- and anti-apoptotic factors. The SHED group showed a significant functional improvement in comparison to the SCI animals, as from the first week until the end of the experiment. This behavioral protection was associated with less tissue impairment and greater motor neuron preservation. SHED reduced neuronal loss over time, as well as the overexpression of pro-apoptotic factor TNF-α, while maintained basal levels of the anti-apoptotic BCL-XL six hours after lesion. Data here presented show that SHED transplantation one hour after SCI interferes with the balance between pro- and anti-apoptotic factors and reduces early neuronal apoptosis, what contributes to tissue and motor neuron preservation and hind limbs functional recovery.

Abstract
INTRODUCTION The pathophysiology of spinal cord injury (SCI) has a classically bad prognosis. It has been demonstrated that human umbilical cord blood stem cells (hUCBSCs) and Melissa officinalis (MO) are useful for the prevention of neurological disease. METHODS Thirty-six adult male rats were randomly divided into intact, sham, control (SCI), MO, hUCBSC, and MO-hUCBSC groups. Intraperitoneal injection of MO (150 mg/kg) was commenced 24 hr post-SCI and continued once a day for 14 days. Intraspinal grafting of hUCBSCs was commenced immediately in the next day. The motor and sensory functions of all animals were evaluated once a week after the commencement of SCI. Electromyography (EMG) was performed in the last day in order to measure the recruitment index. Immunohistochemistry, reverse transcription-polymerase chain reaction, and transmission electron microscopy evaluations were performed to determine the level of astrogliosis and myelination. RESULTS The results revealed that motor function (MO-hUCBSC: 15 ± 0.3, SCI: 8.2 ± 0.37, p < .001), sensory function (MO-hUCBSC: 3.57 ± 0.19, SCI: 6.38 ± 0.23, p < .001), and EMG recruitment index (MO-hUCBSC: 3.71 ± 0.18, SCI: 1.6 ± 0.1, p < .001) were significantly improved in the MO-hUCBSC group compared with SCI group. Mean cavity area (MO-hUCBSC: 0.03 ± 0.03, SCI: 0.07 ± 0.004, p < .001) was reduced and loss of lower motor neurons (MO-hUCBSC: 7.6 ± 0.43, SCI: 3 ± 0.12, p < .001) and astrogliosis density (MO-hUCBSC: 3.1 ± 0.15, SCI: 6.25 ± 1.42, p < 0.001) in the ventral horn of spinal cord were prevented in MO-hUCBSC group compared with SCI group. CONCLUSION The results revealed that the combination of MO and hUCBSCs in comparison with the control group has neuroprotective effects in SCI.

Abstract
OBJECTIVE AND METHODS This study investigated the potential for protective effects of human umbilical cord blood mononuclear cells (UCB-MCs) genetically modified with the VEGF and GNDF genes on contusion spinal cord injury (SCI) in rats. An adenoviral vector was constructed for targeted delivery of VEGF and GDNF to UCB-MCs. Using a rat contusion SCI model we examined the efficacy of the construct on tissue sparing, glial scar severity, the extent of axonal regeneration, recovery of motor function, and analyzed the expression of the recombinant genes VEGF and GNDF in vitro and in vivo. RESULTS Transplantation of UCB-MCs transduced with adenoviral vectors expressing VEGF and GDNF at the site of SCI induced tissue sparing, behavioral recovery and axonal regeneration comparing to the other constructs tested. The adenovirus encoding VEGF and GDNF for transduction of UCB-MCs was shown to be an effective and stable vehicle for these cells in vivo following the transplantation into the contused spinal cord. CONCLUSION Our results show that a gene delivery using UCB-MCs-expressing VEGF and GNDF genes improved both structural and functional parameters after SCI. Further histological and behavioral studies, especially at later time points, in animals with SCI after transplantation of genetically modified UCB-MCs (overexpressing VEGF and GDNF genes) will provide additional insight into therapeutic potential of such cells.

Abstract
The standard treatment of peripherical nerve injuries with substance gap is to introduce the nerve free extremes in a biodegradable tube which, as a biocamera, allows the continuity of the nerve, promote the neuroconduction and save the lesion from the surrounding fibrosis. However, this procedure has not any direct effect on the neuroregeneration nor to resolve high severe lesions. The mesenchymal stem cells (MSC) can derivate "in vitro" in different lineages, including Schwann cells. Different studies have shown MSC can promote the nerve regeneration in rodents, dogs and primates. Moving to the human clinical application requires the procedure standardization, including the optimal cell dose which we have to use. In the sheep model animal we performed a study of 1 cm. nerve section-ressection and repair with a Neurolac™ biocamera, in whose gap we applied between 30 to 50×10(6) MSC from cancellous bone, all of them selected and cultured with GMP procedures. The results were compared with controls (saline serum ± platelet-rich plasma). We used radial nerve (sensitive) and tibial nerve (motor) from 7 sheep. In the first step we performed the surgical lesion and bone marrow aspiration, and in 3 weeks we performed the surgical repair. 3 sheep were sacrificed in 3 months, and 4 sheep in 6 months. In all surgeries we performed a neurophysiological register. When we obtained the tissue samples, we performed an histological, immunohistiquimical and morphometrical study. The recovery percentage was defined comparing the axonal density from the proximal and distal lesion margins. The 3 months samples results were wrong. In 6 months samples results we observed a significative myelined nervous fibers and conduction increasing, in front of controls, both radial and tibial nerves. These results suggest the MSC application in biodegradable scaffold in nerve injuries promotes good results in terms of regeneration and functional recovery.

Abstract
AIM We aim to explore the repair mechanism after the transplantation of CD34(+) human umbilical cord blood cells (HUCBCs) in traumatic spinal cord injury (SCI) in rats. MATERIALS & METHODS Wistar rats with SCI were randomly divided into three groups: DMEM injection (group A); CD34(+) HUCBC transplantation on the first day after injury (group B); and CD34(+) HUCBC transplantation on the sixth day after injury (group C). The Basso, Beattie and Bresnahan scores were used to evaluate motor behavior. At the injured site, the infarct size, blood vessel density, and survival and neural differentiation of transplanted cells were analyzed. RESULTS It was found that the Basso, Beattie and Bresnahan score in group B was significantly higher than other groups (p < 0.05), and the infarct size and blood vessel density at the injured site were significantly different (p < 0.01). However, the transplanted cells survived at least 3 weeks at the injured site, but did not differentiate into neural cells. CONCLUSION These results suggested transplantation of CD34(+) HUCBCs during the acute phase could promote the functional recovery better than during the subacute phase after SCI by raising blood vessel density, suggesting the possible clinical application for the treatment of spinal injury.

Abstract
Umbilical cord blood (UCB) derived multipotent stem cells are capable of giving rise hematopoietic, epithelial, endothelial and neural progenitor cells. Thus suggested to significantly improve graft-versus-host disease and represent the distinctive therapeutic option for several malignant and non-malignant diseases. Recent advances in strategies to isolate, expand and shorten the timing of UCB stem cells engraftment have tremendously improved the efficacy of transplantations. Nervous system has limited regenerative potential in disease conditions such as cancer, neurodegeneration, stroke, and several neural injuries. This review focuses on application of UCB derived stem/progenitor cells in aforementioned pathological conditions. We have discussed the possible attempts to make use of UCB therapies to generate neural cells and tissues with developmental and functional similarities to neuronal cells. In addition, emerging applications of UCB derived AC133+ (CD133+) endothelial progenitor cells (EPCs) as imaging probe, regenerative agent, and gene delivery vehicle are mentioned that will further improve the understanding of use of UCB cells in therapeutic modalities. However, safe and effective protocols for cell transplantations are still required for therapeutic efficacy.
