A recently granted patent (Publication Number: US11969523B2) discloses a composition comprising stem cells, a cell culture medium, and a polyacrylamide hydrogel. The polyacrylamide hydrogel includes acrylamide monomers, a cross-linking agent, and N-hydroxyethyl acrylamide (HEA), with a specific weight percent of HEA. The elasticity modulus of the polyacrylamide hydrogel ranges from 1 to 200 Pa, encapsulating mesenchymal stem cells to support their viability and proliferation. The molar ratio of acrylamide monomers to the cross-linking agent is crucial, falling between 150:1 to 1000:1, ensuring the effectiveness of the composition.

Furthermore, the patent claims cover various aspects of the composition, including the elasticity modulus of the polyacrylamide hydrogel, the dry matter content, and the specific cross-linking agent used. The patent also outlines a detailed process for making the composition, involving the encapsulation of mesenchymal stem cells in the polyacrylamide hydrogel to support their functionality. Additionally, methods for incorporating the composition into a pharmaceutical formulation suitable for human administration and for improving tendon injuries in mammals, including humans, racing mammals like horses, and companion mammals like dogs, are also disclosed. The administration of the composition through injection is highlighted as a preferred method for treating tendon injuries effectively.
