The present invention relates to a population of blood mammalian cells, referred to herein as " blood hepatic tissue cells ", which represent surface markers of unparalleled contours and include a typical characteristic mark of connective tissue connective tissue forming cells.;In particular, it relates to the isolation, characterization and utilization of such hepatic insect tissue cells. The cells of the invention can be distinguished from peripheral blood leukocytes by their distinct size, typology, cell surface phenotype, and biological agent activity, and are also identifiable from connective tissue connective tissue cells by markers of other phenotypes It is possible. These cells proliferate in culture and in vivo, as shown in animal models, and are able to migrate from the blood to the wound site. Thus, such hepatocyte-forming cells include, but are not limited to, enhancement of wound healing, inclusion in cell tissue remodeling and gene therapy, and extensive utility.
