Abstract
As a mechanically condensed product of Coleman fat, extracellular matrix/stromal vascular fraction gel (ECM/SVF-gel) eliminates adipocytes, concentrates SVF cells, and improves fat graft retention. This study aims to compare SVF cell composition between Coleman fat and ECM/SVF-gel. Matched Coleman fat and ECM/SVF-gel of 28 healthy women were subjected to RNA-seq, followed by functional enrichment and cell-type-specific enrichment analyses, and deconvolution of SVF cell subsets, reconstructing SVF cell composition in the transcriptome level. ECM/SVF-gels had 9 upregulated and 73 downregulated differentially expressed genes (DEGs). Downregulated DEGs were mainly associated with inflammatory and immune responses, and enriched in fat macrophages. M2 macrophages, resting CD4+ memory T cells, M1 macrophages, resting mast cells, and M0 macrophages ranked in the top five most prevalent immune cells in the two groups. The proportions of the principal non-immune cells (e.g., adipose-derived stem cells, pericytes, preadipocytes, microvascular endothelial cells) had no statistical differences between the two groups. Our findings reveal ECM/SVF-gels share the same dominant immune cells beneficial to fat graft survival with Coleman fat, but exhibiting obvious losses of immune cells (especially macrophages), while non-immune cells necessary for adipose regeneration might have no significant loss in ECM/SVF-gels and their biological effects could be markedly enhanced by the ECM/SVF-gel's condensed nature.

Study on the Application of PRP Enriched with Hyaluronic Acid to Skin Wounds-Macroscopic Result. CURRENT HEALTH SCIENCES JOURNAL 2022; 48:44-50. [PMID: 35911941 PMCID: PMC9289591 DOI: 10.12865/chsj.48.01.06] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 02/22/2022] [Indexed: 11/18/2022]
Abstract
Tissue healing is a complex process of replacing damaged tissue structures, being a dynamic process with spatial and temporal involvement. In practice, there are three types of healing: primary, secondary and tertiary. Since even tertiary healing can cause different problems depending on the individual patient, the medical world has always strived for new, easier, more effective, faster, and low cost-effective methods to cover skin wounds. This experiment aims to find a method that is as efficient and fast as possible, with minimal costs, of native healing of skin wounds and the development of a protocol that is as reliable and safe as possible for the patient. The experiment was carried out within the animal facility of the University of Medicine and Pharmacy of Craiova, with the agreement of our institutional Ethics Committee. The experimental group consisted of 30 individuals (Wistar laboratory rats), clinically healthy, male and female, being divided into 3 sublots of 10 individuals each. Each sublot was sacrificed at different time intervals: 7, 14 and 21 days, respectively. The local evolution of each individual was monitored during the experimental days, as well as their general state of health. Before slaughter, the lesions were examined macroscopically, following their size, whether or not the infection was present and the presence of other self-inflicted lesions later. Macroscopically, a faster wound healing was found where PRP enriched with hyaluronic acid was applied from the 7th day, so we can say that at first glance the "free" healing period in the case of enhanced epithelialization was about 7 days shorten. This fact will be confirmed or refuted following histopathological examinations and immunohistochemistry.

Angiogenic effects of cell therapy within a biomaterial scaffold in a rat hind limb ischemia model. Sci Rep 2021; 11:20545.

Abstract
Critical limb ischemia (CLI) is a life- and limb-threatening condition affecting 1-10% of humans worldwide with peripheral arterial disease. Cellular therapies, such as bone marrow-derived mesenchymal stem cells (MSCs) have been used for the treatment of CLI. However, little information is available regarding the angiogenic potency of MSCs and mast cells (MC) in angiogenesis. The aim of this study was to evaluate the ability of MCs and MSCs to induce angiogenesis in a rat model of ischemic hind limb injury on a background of a tissue engineered hydrogel scaffold. Thirty rats were randomly divided into six control and experimental groups as follows: (a) Control healthy (b) Ischemic positive control with right femoral artery transection, (c) ischemia with hydrogel scaffold, (d) ischemia with hydrogel plus MSC, (e) ischemia with hydrogel plus MC and (f) ischemia with hydrogel plus MSC and MCs. 106 of each cell type, isolated from bone marrow stroma, was injected into the transected artery used to induce hind limb ischemia. The other hind limb served as a non-ischemic control. After 14 days, capillary density, vascular diameter, histomorphometry and immunohistochemistry at the transected location and in gastrocnemius muscles were evaluated. Capillary density and number of blood vessels in the region of the femoral artery transection in animals receiving MSCs and MCs was increased compared to control groups (P < 0.05). Generally the effect of MCs and MSCs was similar although the combined MC/MSC therapy resulted in a reduced, rather than enhanced, effect. In the gastrocnemius muscle, immunohistochemical and histomorphometric observation showed a great ratio of capillaries to muscle fibers in all the cell-receiving groups (P < 0.05). The data indicates that the combination of hydrogel and cell therapy generates a greater angiogenic potential at the ischemic site than cell therapy or hydrogels alone.

Abstract
Observing the positive effects of PRP (platelet-rich plasma) used in various pathologies, both in traumatology, orthopedics, sports medicine, and in plastic and reconstructive surgery, we decided to develop an improved product, using granular hyaluronic acid. The paper aims at establishing a protocol for obtaining PRP enriched with hyaluronic acid, which can be used in the current practice of treatment of skin defects, safely, with minimal side effects and limited possible, but to provide a shorter healing period as compared to native, "free" healing. The experiment aims to find an effective and rapid method of healing wounds with skin defects, by using a local adjuvant (PRP enriched with hyaluronic acid), which is available to any plastic surgeon. Following the combination of PRP with granular hyaluronic acid, we obtained a product that macroscopically has a gelatinous, viscous consistency, with a good adhesion to the tissues. The potential benefits of this experiment could be the basis for the development of treatment protocols for various pathologies, which result in wounds with skin defects, the most important aspect being the shortening of the classic healing period.

Possible mechanisms underlying the association between human T-cell leukemia virus type 1 (HTLV-1) and hypertension in elderly Japanese population. Environ Health Prev Med 2021; 26:17. [PMID: 33514303 PMCID: PMC7846982 DOI: 10.1186/s12199-021-00938-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Accepted: 01/13/2021] [Indexed: 11/12/2022] Open
Abstract
Background Human T-cell leukemia virus type 1 (HTLV-1) activates inflammatory cascades by activating the NF-κB pathway. The minor allele of single nucleotide polymorphism (SNP) in breast cancer suppressor BRCA1-associated protein (BRAP), which has a common etiology with HTLV-1 infection, has been reported to be positively associated with carotid atherosclerosis, but inversely associated with hypertension. Therefore, HTLV-1 infection may be inversely associated with hypertension by activating endothelial maintenance, including atherosclerosis. To clarify these associations, a cross-sectional study was conducted using 2989 Japanese individuals aged 60–99 years participating in a general health check-up. Methods Logistic regression models were used to clarify the association between HTLV-1 and hypertension. Platelet levels stratified analyses were also performed since platelet production, which plays a crucial role in endothelium maintenance, can be stimulated by activating the NF-κB pathway. Results HTLV-1 infection was found to be significantly inversely associated with hypertension, particularly in subjects with high platelet levels (≥ second tertiles of platelet levels); the fully adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were 0.75 (0.62, 0.92) for total and 0.64 (0.50, 0.82) for high platelet levels, respectively. Further analysis of the non-hypertensive subjects demonstrated that HTLV-1 infection was significantly positively associated with atherosclerosis in subjects with the highest tertile of platelet levels (2.11 [1.15, 3.86]) but not in subjects with low platelet levels (first and second tertiles of platelet level) (0.89 [0.57, 1.39]). Conclusion Asymptomatic HTLV-1 infection is inversely associated with hypertension, possibly by activating endothelial maintenance, including atherosclerosis progression.

Abstract
Excessive fatty acids and glucose uptake support the infiltration of adipose tissue (AT) by a variety of immune cells including neutrophils, pro-inflammatory M1 macrophages, and mast cells (MCs). These cells promote inflammation by releasing pro-inflammatory mediators. The involvement of MCs in AT biology is supported by their accumulation in the AT of obese individuals along with significantly higher serum levels of MC-derived tryptase. AT-resident MCs under the influence of locally derived adipokines such as leptin become activated and release pro-inflammatory cytokines including TNFα that worsens the inflammatory state. MCs support angiogenesis in AT by releasing chymase and inducing preadipocyte differentiation and also the proliferation of adipocytes through 15-deoxy-delta PGJ2/PPARγ interaction. Additionally, they contribute to the remodeling of the AT extracellular matrix (ECM) and play a role in the recruitment and activation of leukocytes. MC degranulation has been linked to brown adipocyte activation, and evidence indicates an important link between MCs and the appearance of BRITE/beige adipocytes in white AT. Cell crosstalk between MCs and AT-resident cells, mainly adipocytes and immune cells, shows that these cells play a critical role in the regulation of AT homeostasis and inflammation.
