Webb10 feb. 2016 · Myelin and Remak Schwann cells develop from immature Schwann cells in perinatal nerves (reviewed in Jessen & Mirsky, 2005). The de-differentiation model of the Schwann cell injury response therefore predicts the generation of a cell in injured nerves that is similar to the immature Schwann cell found in developing nerves prior to … WebbTheodor Schwann, (born December 7, 1810, Neuss, Prussia [Germany]—died January 11, 1882, Cologne, Germany), German physiologist who founded modern histology by defining the cell as the basic unit of animal structure.
