Front Cell Dev Biol 2023; 11:1239448. [PMID: 38033873 PMCID: PMC10687364 DOI: 10.3389/fcell.2023.1239448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 11/01/2023] [Indexed: 12/02/2023] Open
Abstract
Tetraploid complementation is an ideal method for demonstrating the differentiation potential of pluripotent stem cells. In this study, we selected the most efficient tetraploid production method for porcine embryos and investigated whether tetraploid blastomere aggregation could enhance the quality of tetraploid embryos. Three methods were investigated to produce tetraploid embryos: First, tetraploid embryos were produced using electro-fusion of two-cell stage parthenogenetic blastomere (FUTP). Second, somatic cell was injected into the mature oocyte and fused to produce tetraploid embryos. Third, oocytes were matured with Cytochalasin B (CB) for the late 22 h of in vitro maturation to inhibit the first polar body (PB1). Following that, non-PB1 oocytes were treated with CB for 4 h after parthenogenetic activation. There was no significant difference in the blastocyst development rate and tetraploid production rate of the embryos produced through the three methods. However, FUTP-derived blastocysts had a significantly lower percentage of apoptotic cells compared to other methods. The developmental competence of embryos, expression of trophectoderm cell marker genes, and distribution of YAP1 protein were investigated in tetraploid embryos produced using the FUTP method. The FUTP method most effectively prevented apoptosis during porcine tetraploid embryo formation. Tetraploid aggregation-derived blastocysts have a high proportion of trophectoderm with increased expression of the CDX2 mRNA and high YAP1 intensity. High-quality blastocysts derived from a tetraploid embryo aggregation can serve as suitable source material for testing the differentiation potential of pluripotent stem cells for blastocyst complementation in pigs.

Abstract
Chondral defects pose a great challenge for clinicians to manage owing to the limited capacity for self-healing. Various traditional approaches have been adopted for the repair of these defects with unsatisfactory results. Cartilage tissue engineering techniques have emerged as promising strategies to enhance regeneration and overcome these traditional shortcomings. The cell-homing based technique is considered the most promising owing to its unique advantages. Thermosensitive hydrogels have been applied as scaffolds for biomedical applications with smart sol-gel response for altering environmental temperature. Transforming growth factor (TGF)-β1 is considered to be capable of promoting chondrogenesis. In this study, a novel TGF-β1-loaded poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) (PCEC) hydrogel was fabricated using simple procedures. Hydrogel characterization, rheological testing, component analysis, and assessment of sol-gel transition, in vitro degradation, and TGF-β1 release confirmed that this material possesses a porous microstructure with favorable injectability and sustained drug release. Full-thickness cartilage defects were induced on rat knees for in vivo cartilage repair for eight weeks. Micro-CT and histological evaluation provided further evidence of the optimal capacity of this novel hydrogel for cartilage regeneration with respect to that of other methods. Moreover, our results demonstrated that the cell-free hydrogel is thermosensitive, injectable, biodegradable, and capable of in vivo cartilage repair and possesses high potential and benefits for acellular cartilage tissue engineering and clinical application in the future.

The JAK/STAT3 signalling pathway regulated angiogenesis in an endothelial cell/adipose-derived stromal cell co-culture, 3D gel model. Cell Prolif 2016; 50. [PMID: 27667148 DOI: 10.1111/cpr.12307] [Citation(s) in RCA: 53] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2016] [Accepted: 09/01/2016] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES The aim of the study was to investigate the role of the JAK/STAT3 signalling pathway in angiogenesis. MATERIALS AND METHODS The model established in vitro, involved a 3D collagen gel being implanted with endothelial cells (ECs) from red fluorescent protein-labelled mice, and adipose-derived stromal cells (ASCs) from green fluorescent protein-labelled mice. Phenomena of angiogenesis, after treatment by the inhibitor and the activator of JAK/STAT3 pathway respectively, were observed using confocal laser scanning microscopy. Transwell co-culture of ECs and ASCs was used to elucidate mechanisms. RESULTS Stattic, inhibitor of JAK/STAT3 pathway, attenuated angiogenesis in the model. In contrast, angiogenesis was promoted after treatment of Olanzapine, an activator. We found that protein levels of VEGFA and cyclin D1 were regulated by the JAK/STAT3 pathway, and flow cytometry further confirmed variations in cell cycle parameters of ECs and ASCs. Genes VEGFA/B, VEGFR2, MMP-2, MMP-9, IGF-1 and b-FGF were down-regulated by Stattic in ECs, while Olanzapine significantly up-regulated mRNA levels of these genes. As for ASCs, genes VEGFA, MMP-2, MMP-9, IGF-1 and b-FGF were modulated by the JAK/STAT3 pathway. CONCLUSIONS Angiogenesis in the 3D collagen gel was regulated by the JAK/STAT3 pathway which involved changes in vessel length, vessel diameter and sprout number. The underlying mechanism was that the JAK/STAT3 signalling pathway regulated angiogenesis by modulation of numbers of angiogenesis-related growth factors and by direct regulation of cell cycle.

Abstract
OBJECTIVES This study aimed to investigate the influence of hypoxia on angiogenesis in a 3D gel, with co-culturing adipose-derived stromal cells (ASCs) and endothelial cells (ECs). MATERIALS AND METHODS ASCs from green fluorescent protein-labeled mice and ECs from red fluorescent protein-labeled mice were co-cultured in 3D collagen gels at 1:1 ratio, in normal and hypoxic oxygen conditions, and morphology of angiogenesis was observed using confocal laser scanning microscopy. To discover changes in growth factors between monoculture ASCs and ECs, transwell co-cultures of ASCs and ECs were applied. Semi-quantitative PCR was performed to explore mRNA expression of growth factors. RESULTS Enhanced angiogenesis was observed in 3D gels implanted with 1:1 mixture of ASCs and ECs after 7 days hypoxia. Genes including VEGFA/B, EGF-1, HIF-1a, IGF-1, PDGF, TGF-β1 and BMP-2/4 in ECs, both monoculture and co-culture, were significantly enhanced after being cultured under hypoxia. In comparison, genes VEGFA/B, EGF-1, HIF-1a, TGF-β1 and BMP-2 in ASCs increased. In all, factors VEGFA/B, EGF-1, HIF-1a, TGF-β1 and BMP-2 increased in both ASCs and ECs after being cultured in hypoxia no matter whether as monoculture or co-culture. CONCLUSIONS Co-culture of ASCs and ECs at 1:1 ratio in a 3D gel under hypoxia promoted angiogenesis. Those growth factors which were increased in both ASCs and ECs, indicate that VEGFA/B, EGF-1, HIF-1a, TGF-β1 and BMP-2 might be responsible for enhancement in angiogenesis triggered by hypoxia.

Abstract
OBJECTIVES Human amniotic membrane (HAM) has been widely used in soft tissue engineering both in its fresh form and decellularized; its efficiency to aid treatment of burn injuries is well known. On the other hand, it has been reported clinically by several studies that human adipose-derived stem cells (hADSC) are a promising cell source for cell therapy for burns. Recently, we have reported a new technique for decellularization of HAM. In this study, potential of prepared decellularized HAM (dHAM) as a viable support for proliferation and delivery of hADSC was investigated. MATERIALS AND METHODS Amniotic membranes were collected, decellularized and preserved according to the protocol described in our previously published study. hADSC were obtained from the patients undergoing elective liposuction surgery and cells were then seeded on the decellularized membrane for various times. Efficiency of the decellularized membrane as a delivery system for hADSC was investigated by MTT, LDH specific activity, DAPI staining and SEM. RESULTS The results showed that dHAM provided a supporting microenvironment for cell growth without producing any cytotoxic effects. In addition, the cells were spread out and actively attached to the dHAM scaffold. CONCLUSION These results strongly suggest that dHAMs have considerable potential as 3D cell-carrier scaffolds for delivery of hADSC, in tissue engineering and regenerative medicine applications.
