Title

FROM MESENCHYME TO CARTILAGE: LECTIN HISTOCHEMICAL STUDIES OFVENTRO-MEDIAL MESENCHYME TO THE DEVELOPING NEURAL TUBE DURING EMBRYONIC PERIOD

Pages

  100-106

Abstract

 The carbohydrate side-chain of GLYCOCONJUGATEs can show a developmentally regulated expression pattern. In order to analyse these changes during development of mesenchyme ventral to NEURAL TUBE to their cartilagenous fate, two lectins were used to reveal GLYCOCONJUGATEs histochemically in 12 to 16- days old mouse embryos. During days 12 to 13, sclerotomal cells condense around the NOTOCHORD and differentiate into a precartilage ventral to NEURAL TUBE. The results showed that alpha-fucose has no role in differentiation of mesenchyme into cartilage since OFA fail to react with peroxidase-conjugated lectine specific for alpha-fucose. Our finding also revealed that wistaria floribonda (WFA) lectin specific for D-GalNac reacts with sclerotomal cells during precartilage stages. Beginning with day 16 of gestation, all WFA reacted cells differentiate into cartilage of future vertebrate body and intervertebral disc. The results suggest that WFA-positive GLYCOCONJUGATE might play some role in differentiating sclerotomal mesenchyme into cartilage and also may correlate with interaction between NOTOCHORD, NEURAL TUBE and sclerotomal cells in early histogenesis of NEURAL TUBE as well as cartilage formation.
