A polysaccharide micro-particle encapsulating a growth factor is disclosed and shall include one or more growth factors, and a polysaccharide shell forming a space to encapsulate the growth factor by electrostatic interaction. Also, a method for manufacturing a polysaccharide micro-particle encapsulating a growth factor is disclosed, which shall include the following process: (A) providing a pH 4.6-6 polysaccharide solution and a growth factor; and (B) adding the growth factor to the polysaccharide solution, and adjusting the polysaccharide solution to a pH of 6-8 to obtain the polysaccharide micro-particle encapsulating the growth factor by electrostatic interaction. According to the polysaccharide shell structure, the growth factor can be stored for a long period of time and heal skin wounds, mucositis, and corneal ulcer effectively. |
