Abstract
The sheaths of the damaged peripheral nerve of Wistar-Kyoto rats were studied after single subperineural administration of bromodeoxyuridine (BrdU)-labeled bone marrow mesenchymal stem cells (MSC) from the same rats. The sciatic nerve was damaged by ligation for 40 sec directly before MSC administration. BrdU+ MSC were identified in the recipient nerve within 1 week after transplantation and were detected not only in the endoneurium, but also in the epineurium and perineurium. It was found that single administration of MSC into the damaged nerve trunk led to an almost 2-fold increase in the thickness of its sheaths (perineurium and epineurium) in comparison with the control group (ligation). It can be hypothesized that MSC induce thickening of nerve sheaths through the production of factors that stimulate angiogenesis and adipogenesis.

Functional Activity of Non-Proliferating Mesenchymal Stromal Cells Cultured at Different Densities. Bull Exp Biol Med 2021; 170:537-543.

Abstract
We analyzed the state of intracellular compartments and production of cytokines in MSC depending on the culture density. MSC were growth-arrested with mitomycin C and seeded at a density of 300-7000 cell/cm2. MSC in low-density cultures had 2-fold higher levels of transmembrane mitochondrial potential (MitoTracker Red) and endogenous ROS (CMH2DCFDA), lysosomal compartments were less acidified (LysoTracker Green DND26), the production of immunoregulatory and angiogenic mediators VEGF, IL-6, IL-8, MCP-1, TGF-β was more intensive. It was assumed that culture density can be an effective tool for phenotypic polarization of MSC providing directional changes in their properties.

Multipotent stromal cells stimulate liver regeneration by influencing the macrophage polarization in rat. World J Hepatol 2018; 10:287-296. [PMID: 29527264 PMCID: PMC5838447 DOI: 10.4254/wjh.v10.i2.287] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 10/31/2017] [Accepted: 02/06/2018] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate the influence of the umbilical cord-derived multipotent stromal cells (MSCs) on recovery of the liver after the subtotal resection, that is, removal of 80% of the organ mass, a renowned model of the small-for-size liver remnant syndrome.
METHODS The MSCs were obtained from the intervascular tissue of umbilical cords, dissected from rat fetuses, by the explant culture technique. The vital labeling of MSCs with РКН26 was carried out on the 3rd passage. The subtotal resection was performed on male Sprague-Dawley rats. The experimental group animals received a transplant 106 MSCs infused into the spleen. Hepatocyte proliferation was assessed by counting of either mitotic figures or Ki67-positive cells in microscopic images. MSC differentiation was assessed with antibodies to hepatocyte-specific marker cytokeratin 18 (CK18), cholangiocyte-specific protein CK19, smooth muscle cell-specific protein α-SMA, the endothelial cell marker CD31, or the active fibroblast marker FAPα. Total macrophages of the liver were selectively stained in cryosections incubated with anti-CD68 antibodies (1:100, Abcam), while the M2a and M2c macrophage populations were selectively stained with anti-CD206 antibodies. Expression of interleukin and growth factor genes was evaluated with PCR-RT.
RESULTS Intrasplenic allogeneic transplantation of the umbilical cord-derived multipotent stromal cells stimulates reparative processes within the residual liver tissue after subtotal resection (removal of 80% of the organ mass), as indicated by increased rates of hepatocyte proliferation and accelerated organ mass recovery. These effects may result from paracrine influence of the transplanted cells on the resident macrophage population of the liver. The transplantation favors polarization of macrophages to M2 phenotype (the M2-polarized macrophages specifically express CD206; they are known to suppress inflammation and support tissue repair). No differentiation of the transplanted cells into any of the liver cell types have been observed in the study.
CONCLUSION We found no direct evidence for the paracrine effect of MSCs on liver regeneration after the subtotal liver resection in rats. However, the paracrine mechanism of the therapeutic activity of transplanted MSC is indirectly indicated by a decrease in the total number of CD68 + macrophages and an increase in the proportion of M2 pro-repair macrophages in the regenerating liver as compared to animals in which the transplantation was only mimicked.

Abstract
The common prevalence of heart failure and limitations in its treatment are leading cause of attention and interest towards the induction of cardiac regeneration with novel approaches. Recent studies provide growing evidence regarding bona fide cardiac regeneration post genetic manipulations, administration of stimulatory factors and myocardial injuries in animal models and human studies. To this end, stem cells of different sources have been tested to treat heart failure for the development of cellular therapies. Endogenous and exogenous stem cells sources used in regenerative cardiology have provided a proof of concept and applicability of cellular therapies in myocardial improvement. Recent clinical studies, especially, based on the endogenous cardiac progenitor and stem cells highlighted the possibility to regenerate lost cardiomyocytes in the myocardium. This review discusses emerging concepts in cardiac stem cell therapy, their sources and route of administration, and plausibility of de novo cardiomyocyte formation.

Abstract
We studied the effect of a biomedical cell product (bone marrow multipotent mesenchymal stromal cells and products secreted by these cells in conditioned medium) on subpopulation composition of lymphoid cells of central and peripheral lymphoid organs of Wistar rats under normal conditions. Changes in the subpopulation composition of lymphoid organs depended on the route of administration of biomedical cell product.
