ABSTRACT
Using a TV device for studying microcirculation (×40), we analyzed the density of the whole microvascular network and the density of arterioles in the pia mater of the sensorimotor cortex in SHR rats of different ages (3-4 and 12 months) after intracerebral transplantation of human mesenchymal stem cells. We found that the density of pial microvascular network in SHR rats receiving transplantation of human mesenchymal stem cells increased to a level observed in young Wistar-Kyoto rats.

We studied the effect of platelet lysates from different donors on fibroblast growth in culture. In most samples (40 of 50), the growth-stimulating characteristics were greater than in 10% FCS, but every ninth sample exhibited low mitogenic activity. A weak dependence between platelet concentration and total protein content was noted, but no correlation was found between these parameters and fibroblast growth in culture.
