31. PSA expression does not occur on Schwann cells . 32. The mouse version ( orthologue ) of SH3TC2 is believed to be expressed in Schwann cells . 33. He discovered the cells that envelope the nerve fibers, now called Schwann cells in his honor. 34. Schwann cells were tranduced with a retroviral vector encoding STX in order to induce PSA expression.35. Next two very similar autoimmune response which affects the Schwann cells in the peripheral nervous system. 36. Once a nonmyelinating Schwann cell has suffered inactivation of its NF1 genes, it begins to proliferate rapidly. 37. They used spider silk fibers to create a nerve conduit with Schwann cells and acellularized xenogenic veins. 38. Macrophages also play a role in inducing the proliferation of Schwann cells that occurs during Wallerian degeneration. 39. These cells share a common ancestor with both Myelinating and Non-Myelinating Schwann Cells called Neural Crest cells. 40. Each participant s own Schwann cells have been successfully transplanted into four subjects with no adverse effects.
