BACKGROUND AIMS Human adult bone marrow (BM)-derived mesenchymal stromal cells (hMSC) are reported to break germ layer commitment and differentiate into cells expressing neuroectodermal properties. Although it is of pivotal interest for cell replacement therapies for neurologic disorders, no data exist on the influence of the donor's age on this multipotent(More)
Chromaffin cells of the adrenal medulla are neural crest-derived cells of the sympathoadrenal lineage. Unlike the closely-related sympathetic neurons, a subpopulation of proliferation-competent cells exists even in the adult. Here, we describe the isolation, expansion, and in vitro characterization of proliferation-competent progenitor cells from the bovine(More)
Chromaffin cells, sympathetic neurons of the dorsal ganglia, and the intermediate small intensely fluorescent cells derive from a common neural crest progenitor cell. Contrary to the closely related sympathetic nervous system, within the adult adrenal medulla a subpopulation of undifferentiated progenitor cells persists, and recently, we established a(More)
Chromaffin cells of the adrenal medulla are neural crest-derived cells of the sympathoadrenal lineage. Different lines of evidence suggest the existence of a subpopulation of proliferation-competent progenitor cells even in the adult state. The identification of sympathoadrenal progenitors in the adrenal would greatly enhance the understanding of adrenal(More)
The differentiation of dopamine-producing neurons from chromaffin progenitors might represent a new valuable source for replacement therapies in Parkinson's disease. However, characterization of their differentiation potential is an important prerequisite for efficient engraftment. Based on our previous studies on isolation and characterization of(More)
The antiepileptic drug valproic acid (VPA) has been shown to influence the neural differentiation and neurite outgrowth of neural stem cells. Sympathoadrenal progenitor cells share properties with neural stem cells and are considered a potential cell source in the treatment of neurodegenerative diseases. The present study therefore aims at modulating the(More)
Chromaffin cells probably are the most intensively studied of the neural crest derivates. They are closely related to the nervous system, share with neurons some fundamental mechanisms and thus were the ideal model to study the basic mechanisms of neurobiology for many years. The lessons we have learned from chromaffin cell biology as a peripheral model for(More)
We present a method to efficiently culture primary chromaffin progenitors from the adult bovine adrenal medulla in a defined, serum-free monolayer system. Tissue is dissociated and plated for expansion under support by the mitogen basic fibroblast growth factor (bFGF). The cultures, although not homogenous, contain a subpopulation of cells expressing the(More)
The potential use of neural stem cells in basic research, drug testing and for development of therapeutic strategies requires large scale in vitro amplification, increasing the probability of genetic instability and transformation. Little is known, however, about potential correlations between long-term culture of neural stem and progenitor cells (NSPCs),(More)
