Schwann cells derived from stromal bone marrow cells

摘要

A method for differentiation and inducing in vitro myeloid interstitial cells into Schwann cells originating in the myeloid interstitial cells comprises collecting myeloid interstitial cells from bone marrow before culturing in a medium prepared by adding serum to a standard fundamental medium with additives. A method for differentiation and inducing in vitro myeloid interstitial cells into Schwann cells originating in the myeloid interstitial cells comprises: (a) collecting myeloid interstitial cells from bone marrow before culturing in a medium prepared by adding serum to a standard fundamental medium; (b) adding a reducing agent to the liquid medium then continuing the culture; (c) adding a differentiation-inducing agent to the liquid medium and further culturing; and (d) adding a cyclic AMP-elevating agent or a cyclic AMP analog and/or a gliacyte-differentiation survive function factor to such liquid medium and continuing the culture to form Schwann cells. Independent claims are also included for the following: (1) Schwann cells originating in myeloid interstitial cells optionally obtained by differentiation and induction; (2) drug compositions for nerve regeneration containing the Schwann cells; and (3) a method for treating neuropathy by transplanting the Schwann cells or drug compositions to patients with neuropathy to promote regeneration of nerve cells in the patient. ACTIVITY : Nootropic; neuroprotective. No biological data given. MECHANISM OF ACTION : Gene therapy. No biological data given.
