Abstract:
To localize glycoconjugates of surface mucous cells, mucous neck cells and chief cells in the developing rat, nine of biotinylated lectin(SBA, DBA, PNA, BSL-1, RCA-1, sWGA, UEA-1, Con A and LCA) were applied with ABC method. In the surface and gastric pit epithelium of body of the stomach, DBA affinity was not demonstrated. Although Con A and LCA affinity were slightly increased after birth, these affinities with RCA-1 and sWGA maintained constantly from fetal to adult rat. And UEA-1 affinity gradually increased from the end of suckling period. BSL-1 and PNA affinity showed a tendency to decrease and was not observed in most cells from the suckling and weanling period respectively. In the gastric gland proper, mucous neck cells and chief cells were not distinguished until the early weanling period. All affinities examined except DBA and BSL-1 were observed and increased in the gland of postnatal rat. With the approach of weanling period, more intense affinity for PNA, RCA-1, sWGA and UEA-1 were found on lower portion of the gastric gland proper and more intense affinity for SBA on upper portion. The mucous neck cells showed a similar affinities as gastric gland proper from the weanling period and two affinities for PNA and Con A were detected in the chief cell.
