NEW STRUCTURAL PROTEIN PREPARATIONS, THEIR METHOD OF MANUFACTURE AND APPLICATIONS

摘要

Novel proteinaceous skeleton preparations were described, devoid of proteins susceptible to mammalian proteolytic enzymes as well as a method of obtaining these preparations, particularly keratin-based, encompassing the use of repeated chemical activation, enzymatic digestion and grinding of the obtained keratinous preparations, as well as the application of the proteinaceous skeleton preparations, particularly as a carrier for use in stem cell cultures. Proteinaceous skeleton preparations resistant to enzymatic digestion may widespread find use in medicine as a carrier material for cell cultures, preferentially of stem cells.
