Abstract
The present invention provides methods of inducing proliferation of and/or differentiating cells comprising contacting cells with compounds within the methods of the invention. The present invention further provides cells obtainable by the methods of the invention. Liver disease affects more than 500 million people worldwide. Organ transplantation is the gold standard for treatment of liver failure, but organ shortages are acute.

- and,
- n is 0, 1, 2, 3, 4 or 5;
- a compound of Formula (II):
- wherein in (II):
- W is H, F, Cl, Br, I, OH, lower alkyl or lower alkoxy;
- X is F, Cl, Br or I;
- each occurrence of R is independently H or lower alkyl;

- a compound of Formula (III):
- wherein in (III):
- G is C(R)2, O or N(R);
- each occurrence of Q is independently O or N(R);
- each occurrence of R is independently H or lower alkyl;
- each occurrence of Y is independently C(═O) or S(O)2;

- each occurrence of R15 is independently OH, F, Cl. Br, I, NH2, CN, NO2, lower alkyl, or lower alkoxy;
- and,
- n is 0, 1 or 2;
- a compound of Formula (V):
- wherein in (V):
- each occurrence of R is independently H or lower alkyl;
- Q is a bond, O or NR;
- Y is C═O or S(O)2, preferably C═O;
- R21 is substituted or unsubstituted alkyl, aralkyl, cycloalkyl, aryl or heteroaryl;

- enantiomers or diastereoisomers thereof, prodrugs thereof, pharmaceutically acceptable salts thereof, and any combinations thereof,
- whereby contacting the one or more primary cells with the at least one compound induces proliferation of the one or more primary cells.
4-13. (canceled)
A method of inducing differentiation of one or more induced pluripotent stem cells (iPS cell), the method comprising contacting the one or more iPS cells with at least one compound selected from the group consisting of Compounds 109-114, a compound of Formula (I)-(V), enantiomers or diastereoisomers thereof, prodrugs thereof, pharmaceutically acceptable salts thereof, and any combinations thereof, whereby contacting the one or more iPS cells with the at least one compound induces differentiation of the one or more iPS cells.
