Fibroblast Growth Factors and Insulin Growth Factors Combine to Promote Survival of Rat Schwann Cell Precursors Without Induction of DNA Synthesis
In embryonic rat nerves, we recently identified an early cell in the Schwann cell lineage, the Schwann cell precursor. We found that when these cells were removed from contact with axons they underwent rapid apoptotic death, and that in a proportion of the cells this death could be prevented by basi...

520 | |a In embryonic rat nerves, we recently identified an early cell in the Schwann cell lineage, the Schwann cell precursor. We found that when these cells were removed from contact with axons they underwent rapid apoptotic death, and that in a proportion of the cells this death could be prevented by basic fibroblast growth factor (bFGF, FGF-2). We now report that 100% of Schwann cell precursors isolated from peripheral nerves of 14-day-old-rat embryos can be rescued by a combination of insulin-like growth factor (IGF) 1 or 2 in combination with either acidic FGF (aFGF, FGF-1), bFGF or Kaposi's sarcoma FGF (K-FGF; FGF-4). The precursors display an absolute requirement for both an IGF and an FGF to achieve maximal survival. Elevation of intracellular levels of cAMP by forskolin does not result in a significant shift in the IGF/FGF dose-response curves. In contrast, the percentage of precursors rescued by FGF in the presence of insulin is dramatically increased by elevation of cAMP. These growth factor combinations did not stimulate DNA synthesis significantly in Schwann cell precursors. These findings show that cooperation between growth factors is required to suppress cell death in Schwann cell precursors, and suggest that survival and DNA synthesis are regulated by distinct growth factor combinations in these cells. The observations are consistent with the idea that survival regulation by FGFs and IGFs plays an important role in the development of glial cells in early embryonic nerves. | ||

Fibroblast Growth Factors and Insulin Growth Factors Combine to Promote Survival of Rat Schwann Cell Precursors Without Induction of DNA Synthesis |
abstract |
In embryonic rat nerves, we recently identified an early cell in the Schwann cell lineage, the Schwann cell precursor. We found that when these cells were removed from contact with axons they underwent rapid apoptotic death, and that in a proportion of the cells this death could be prevented by basic fibroblast growth factor (bFGF, FGF-2). We now report that 100% of Schwann cell precursors isolated from peripheral nerves of 14-day-old-rat embryos can be rescued by a combination of insulin-like growth factor (IGF) 1 or 2 in combination with either acidic FGF (aFGF, FGF-1), bFGF or Kaposi's sarcoma FGF (K-FGF; FGF-4). The precursors display an absolute requirement for both an IGF and an FGF to achieve maximal survival. Elevation of intracellular levels of cAMP by forskolin does not result in a significant shift in the IGF/FGF dose-response curves. In contrast, the percentage of precursors rescued by FGF in the presence of insulin is dramatically increased by elevation of cAMP. These growth factor combinations did not stimulate DNA synthesis significantly in Schwann cell precursors. These findings show that cooperation between growth factors is required to suppress cell death in Schwann cell precursors, and suggest that survival and DNA synthesis are regulated by distinct growth factor combinations in these cells. The observations are consistent with the idea that survival regulation by FGFs and IGFs plays an important role in the development of glial cells in early embryonic nerves. |
