Porous nanofiber mesh for three-dimensional cell culture
View Patent ↗Disclosed is a mesh for cell culture in which linear nanofiber is cross-linked to form a network, wherein the linear nanofiber is composed of polyhydroxyalkanoate; or polyhydroxyalkanoate, and collagen, gelatin or their mixture. The mesh for cell culture of the present invention can culture cell since the cell, more preferably the cancer cell is easily stuck to the mesh because of its structural characteristics and effect of the added collagen or gelatin, and also to smoothly supply nutrients, oxygen, etc. through connected pores. In particular, the mesh for cell culture of the present invention may be useful to culture the cancer cell.
1. A porous mesh for cell culture capable of being used for a three-dimensional cell culture, said mesh comprising nanofibers cross-linked to each other to form a network, wherein the nanofibers are formed of mixture of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and collagen, and
wherein the mixture comprises a weight ratio of collagen to poly(3-hydroxybutyrate-co-3-hydroxyvalerate) of 2-10%.
2. A porous mesh for cell culture capable of being used for a three-dimensional cell culture, said mesh comprising nanofibers cross-linked to each other to form a network, wherein the nanofibers are formed of a mixture of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and gelatin, and
wherein the mixture comprises a weight ratio of gelatin to poly(3-hydroxybutyrate-co-3-hydroxyvalerate) of 10-100%.
3. The mesh for cell culture according to claim 1 , wherein each of the nanofibers has a diameter in the range of 50 to 2,000 nm.
4. The mesh for cell culture according to claim 2 , wherein each of the nanofibers has a diameter in the range of 50 to 2,000 nm.
