  • Method for culturing differentiation-promoting and -sustaining spheroid form of tonsil-derived stem cells
    Patent number: 10870830
    Abstract: The present invention relates to a method for producing a spheroid form of tonsil-derived stem cells, the method enhances growth and differentiation efficiency of the tonsil-derived stem cells. The present method also produces a spheroid form of para-thyroid hormones. The method for producing a spheroid form of tonsil-derived stem cells enhances the proliferation rate of the stem cells per se and significantly increase differentiation potency into parathyroid cells.

  • METHOD FOR CULTURING DIFFERENTIATION-PROMOTING AND -SUSTAINING SPHEROID FORM OF TONSIL-DERIVED STEM CELLS
    Publication number: 20190194611
    Abstract: The present invention relates to: a method for producing a spheroid form of tonsil-derived stem cells, the method enhancing growth and differentiation efficiency of tonsil-derived stem cells; and a method for producing a spheroid form of parathyroid hormones from the same. The method of the present invention for producing a spheroid form of tonsil-derived stem cells cultures the tonsil-derived stem cells in the form of a spheroid to thereby enhance the proliferation rate of the stem cells per se and remarkably increase differentiation potency into parathyroid cells. Thereby, the method has a remarkable effect on the growth and differentiation of the tonsil-derived stem cells into parathyroid cells, etc.
