Abstract:
Objective To study the role of different subtypes of PKC in the neurite outgrowth of primary cultured neurons from embryonic rat spinal cord. Methods We observed the expression and distribution of protein kinase C(?、?Ⅰ、?Ⅱ、? subtypes) by using immunohistrochemical technique in the neurite outgrowth of the primary cultured neurons from the embryonic rat spinal cord by means of computer image analysis system to measure the lengths of neurites and the areas of bodies. Results The areas of the cultured neuronal bodies increased and the neurites prolonged while the expression of the four subtypes of PKC gradually increased before 7div(day in vitro )during primary cultured neurons growth. The expression both in bodies and neurites of neurons decreased after 7div and the processes gradually shrinked and at the same time bubbles appeared inside the bodies. Relative assay demonstrated that ?Ⅱ subtype was most relative to the outgrowth of neurites( r =0 73, P
