Abstract: A substance P analog having a progenitor cell or stem cell recruiting activity and a method of recruiting progenitor cells or stem cells using the substance P analog are disclosed. The substance P analog has an effect of recruiting endogenous progenitor cells or stem cells to a wound or disease-occurring site. Thus, the disclosure also describes its use in recruiting progenitor cells or stem cells and a method of regenerating or treating a damaged organ or tissue, or a method of healing a wound.

Abstract: The present invention relates to an injectable hydrogel composition having the recruitment of endogenous progenitors or stem cells and the induction of vascular differentiation of recruited cells, and more specifically to an injectable hydrogel composition having the recruitment of endogenous progenitors or stem cells and the induction of vascular differentiation of recruited cells, which consists of: a first solution including anionic hyaluronic acid into which a vascular differentiation inducing factor is introduced; and a second solution including a cationic material, wherein a stem cell recruitment factor is further included in the first solution and/or the second solution, and wherein a hydrogel is formed by electrostatic interaction.
In the hydrogel composition of the present invention, it was confirmed that the stem cell recruitment factor was released from the injected hydrogel, and endogenous progenitor cells/stem cells were recruited in the hydrogel, and the induction of angiogenesis was promoted by differentiating into vascular cells by the vascular differentiation inducing factor chemically introduced into hyaluronic acid. In particular, it was confirmed that when the vascular differentiation inducing factor was chemically introduced into hyaluronic acid, a high angiogenesis-inducing effect was observed. Therefore, the hydrogel composition of the present invention has excellent recruitment of endogenous progenitor cells/stem cells and induction of vascular differentiation, and thus, it can be effectively applied to various tissue regenerations and wound treatments in addition to the formation of blood vessels.
