Comparative Microarray Analysis of Proliferating and Differentiating Murine ENS Progenitor Cells.

Postnatal neural progenitor cells of the enteric nervous system are a potential source for future cell replacement therapies of developmental dysplasia like Hirschsprung's disease. However, little is known about the molecular mechanisms driving the homeostasis and differentiation of this cell pool. In this work, we conducted Affymetrix GeneChip experiments to identify differences in gene regulation between proliferation and early differentiation of enteric neural progenitors from neonatal mice.

Isolation, expansion and transplantation of postnatal murine progenitor cells of the enteric nervous system.

Neural stem or progenitor cells have been proposed to restore gastrointestinal function in patients suffering from congenital or acquired defects of the enteric nervous system. Various, mainly embryonic cell sources have been identified for this purpose. However, immunological and ethical issues make a postnatal cell based therapy desirable.

Molecular and cell biological effects of 3,5,3'-triiodothyronine on progenitor cells of the enteric nervous system in vitro.

Introduction: Thyroid hormones play important roles in the development of neural cells in the central nervous system. Even minor changes to normal thyroid hormone levels affect dendritic and axonal outgrowth, sprouting and myelination and might even lead to irreversible damages such as cretinism. Despite our knowledge of the influence on the mammalian CNS, the role of thyroid hormones in the development of the enteric nervous system (ENS) still needs to be elucidated.
