Abstract: The present invention relates to a method of removing undifferentiated stem cells and dedifferentiated stem cells from a sample of cells. The invention further relates to preventing dedifferentiation of differentiated cells. Both methods comprise of administering to said cells an effective amount of compounds of formula (I): or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3, n, p, Z and T are defined herein.

Abstract: The present invention relates to the use of a compound represented by the general formula (I), and pharmaceutically acceptable salts thereof, wherein: n is an integer from 2 to 5; p is an integer from 0 to 4; R1 is selected from the group consisting of a hydroxyl group, an alkoxy group, a thiol group, a thioether group, and an amino group, wherein at least two of R1 is a hydroxyl group, a thiol group or an amino group, with the proviso that wherein n is 2, R1 is not on the carbon-2 position and the carbon-5 position of the phenyl group; R2 and R3 are independently a methylene group or a nucleophile, with the proviso that at least one of R2 and R3 is a nucleophile group; Z is an oxygen (O) atom or sulfur (S) atom; T is hydrogen or an optionally substituted aliphatic group; in the manufacture of a medicament for treating a patient in need of cell therapy.
