Endometrial mesenchymal stem cells isolated from the menstrual blood.

Stem cells from the endometrium isolated during menstrual bleeding were characterized. By their main surface markers, differentiation potential, and morphological signs these cells belong to mesenchymal stem cells. Specific features of this cell type are high clonogenic activity and low capacity to adipocyte differentiation.

Experimental intravenous cell therapy of acute and chronic renal failure.

The therapeutic effect of intravenous injection of human fetal bone marrow mesenchymal stem cells or summary culture of kidney cells were studied on models of chronic or acute renal failure in outbred albino rats. Both cell types promoted improvement and normalization of the renal function in rats with stable chronic renal insufficiency (2 weeks after kidney cell injection, 1 month after bone marrow mesenchymal stem cell injection). Renal function remained normal or subnormal during the delayed period (3-3.

Umbilical cord blood mesenchymal stem cells.

We studied umbilical cord blood mesenchymal stem cells and compared mesenchymal stem cells derived from umbilical cord blood, adipose tissue, and skin. Umbilical cord blood mesenchymal stem cells were characterized morphologically, cytofluorometrically, and by their differentiation potential. Umbilical cord blood mesenchymal stem cells did not differ from cells isolated from adipose tissue and skin by the main parameters (by morphology, expression of surface markers, and differentiation potential).

Functional aftereffects of intraparenchymatous injection of human fetal stem and progenitor cells to rats with chronic and acute renal failure.

Chronic renal insufficiency was modeled in rats by unilateral nephrectomy and electrocoagulation of both poles of the remaining kidney; acute renal failure was induced by 90-min clamping of the vascular pedicle of the only kidney. Injection of unfractionated culture of human fetal kidney cells or bone marrow mesenchymal stem cells into damaged kidney restored its function in rats with chronic renal insufficiency (observation period up to 2 months). After 2.

Differentiation potential of mesenchymal stem cells of different origin.

We compared differentiation potential of mesenchymal stem cells originating from human bone marrow, fatty tissue, thymus, placenta, and skin. The cells were characterized by differentiation into adipocytes and osteoblasts. Mesenchymal stem cells from different sources exhibited different differentiation potential, manifesting by the rate of differentiation and percentage of differentiated cells.
