Potencialidad celular evolutiva y medicina regenerativa

Abstract

Embryoblast derived cells or inner cell mass (ICM) of blastocysts correspond to embryonic stem cells, are pluripotent them, because they have the capacity to generate all cell lines and the remainder are known as stem cells adults because they have the potential for much more restricted differentiation. Within cells can recognize adult hematopoietic stem cells and bone marrow mesenchymal stem cells present in nearly all connective tissues and intended adult tissue repair and regeneration. They have been described as part of the bone marrow, umbilical cord mesenchyme in adipose tissue and nerve tissue. The collection and use of embryonic stem cells and adult tissues is the subject of current interest in a new area of medicine that aims to regenerate organs and functions. In this paper, we analyze the most interesting aspects of obtaining stem cells, with their projections in human and veterinary medicine.
