Cytological Aspects of the Differentiation of Barb Cells During the Formation of the Ramus of Feathers
Int. j. morphol; 25 (1), 2007
The present ultrastructural study on developing and regenerating feathers of chick and zebrafinch describes the ultrastructural changes that occur during the differentiation of barb cells that leads to the formation of the ramus of barbs. Differently from barbule and barb cortical cells that accumulate f...
