We have investigated the characteristics of human hematopoietic progenitor cells (HPCs) with the CD34(+)CD45(low)SSC(low) phenotype from full-term placental tissue (FTPT) as compared to cord blood (CB) and fetal liver (FL) cells. We demonstrated the presence of cell subpopulations at various stages of the differentiation with such immunophenotypes as CD34(+/low)CD45(low/-), CD34(++)CD45(low/-), CD34(+++)CD45(low/-), CD34(+/low)CD45(hi), and CD34(++)CD45(hi) in both first trimester placental tissue (FiTPT) and FTPT which implies their higher phenotypic heterogeneity compared to CB. HPCs of the FTPT origin expressed the CD90 antigen at a higher level compared to its expression by the CB HPCs and the CD133 antigen expression being at the same level in both cases. The HPCs compartment of FTPT versus CB contained higher number of myeloid and erythroid committed cells but lower number of myeloid and lymphoid ones compared to FL HPCs. HPCs of the FTPT and CB origin possess similar potentials for the multilineage differentiation in vitro and similar ratios of myeloid and erythroid progenitors among the committed cells. This observation suggests that the active hematopoiesis occurs in the FTPT. We obtained viable HPCs from cryopreserved placental tissue fragments allowing us to develop procedures for banking and testing of placenta-derived HPCs for clinical use.

Currently, the development and the implementation of the new biotechnological wound coverings (skin equivalents) designed for temporal or permanent replacement of damaged or destroyed areas of human skin remains extremely actual relevant in clinical practice. Skin equivalents or equivalents of individual skin layers which include alive cells of different types take a special place among the artifi cial wound coverings. They mostly contain two basic types of cells – fi broblasts and keratinocytes (together or separately). Such bioconstructions are usually served as temporary coverings, which supply the damaged skin by biologically active substances and stimulate the regeneration of the patient's own tissues. In this review we consider as commercially available wound coverings and those which are still studied in the laboratories. Until now ideal substitutes of natural skin have not yet created, so the efforts of many researchers are focusing on the solution of this problem.

The study of placental hematopoietic progenitor cells (HPCs) and comparison of their properties with other fetal and adult HPCs is necessary for assessing of their possible clinical application. It has been shown that HPCs from placenta are heterogeneous by phenotype: placental tissue contains three populations with different level of CD34 expression such as CD34
