Patent number: 12668775Abstract: The present invention provides a method for reprogramming a human somatic cell to a cell exhibiting at least one characteristic of a trophoblast stem cell (TSC), the method comprising the following steps in order: a) increasing the protein expression of one or more factors in the somatic cell, wherein the factors are for reprogramming the somatic cell towards a pluripotent state; b) culturing the cell for a sufficient time and under conditions to allow the reprogramming of the cell towards a pluripotent state; c) contacting the cell with a culture medium suitable for sustaining trophoblast stem cells (TSC); and d) culturing the cell in the TSC medium for a sufficient time and under conditions to allow the cell to exhibit at least one characteristic of a TSC, thereby reprogramming the somatic cell to a cell exhibiting at least one characteristic of a TSC.Type: GrantFiled: November 13, 2020Date of Patent: June 30, 2026Assignees: Monash University, National University of Singapore, NANTES UNIVERSITEInventors: Jose Polo, Xiaodong Liu, Kathryn Davidson, Owen Rackham, John F.
