Isolation and characterization of a glycoprotein from human colostrum.
نویسندگان
چکیده
A glycoprotein was isolated from the M-1 acid glycoprotein fraction of human colostrum. It had a molecular weight of 31200 and contained 27% galactose, 21.7% hexosamine, 8.0% fucose and 10.8% sialic acid by weight. The glycoprotein had no absorption maxima in the 240-300nm region, and was virtually free of ABH(O) and M and N blood-group activity. Alkaline borohydride cleavage of the glycoprotein resulted predominantly in the destruction of threonine and galactosamine.

Isolation and in vitro Characterization of Mesenchymal Stem Cells Derived from the Pulp Tissue of Human Third Molar Tooth
Background: It is still controversial that the stem cells isolated from human dental pulp meets the criteria for mesenchymal stem cells (MSCs). The aim of the present study was to examine whether or not they are MSCs, or are distinct stem cells population residing in tooth pulp. Methods: Adherent fibroblastic cells in the culture of pulp tissue from human third molars were propagated through se...
