摘要:
본 발명은 중간엽줄기세포의 조정 배지 유래 엑소좀을 유효성분으로 포함하는 개과 동물의 정액 동결보존용 조성물에 관한 것으로, 본 발명의 동결보존용 조성물은 개과 동물의 정액에 대해 동결융해 후에 정자의 운동성, 생존율, 정자막 안정성 및 점액질 통과능을 향상시키는 효과가 우수하므로, 개과 동물의 종 개량 또는 혈통 보존 등을 위한 체외 번식기술에 유용하게 활용될 수 있을 것이다.
摘要:
The present invention provides a method for processing cultured cells. The method includes the steps of providing a biochamber for culturing cells; providing a culture media for culturing cells within the biochamber; inoculating the biochamber with cells; culturing the cells; upon a predetermined time period of culture, displacing the culture media from the biochamber with a biocompatible first rinse solution; replacing the first rinse solution with a cell harvest enzyme solution; incubating the contents of the biochamber for a predetermined period of time, wherein during incubation, the enzyme at least dissociates the cells from each other and/or from the biochamber surface; and displacing the enzyme solution with a second rinse solution, wherein upon the enzyme being displaced, the chamber is substantially filled with the second rinse solution.

PROBLEM TO BE SOLVED: To provide compositions and methods for tissue repair.SOLUTION: The present invention provides a fluid exchange cell culture technique and tissue repair cells made by these methods, as well as methods using these cells. The method includes a new wash step which increases the tissue repair properties of the TRCs. This wash step allows for the production of TRC populations with greater tissue repair and anti-inflammatory capabilities. Embodiments of the present invention include a post-culture process for cultured cells that preferably includes the steps of: a wash process for removing unwanted residual culture components, a volume reduction process, and a harvesting process to remove cultured cells. The final composition is a substantially purified and concentrated cell mixture suspended in a physiologic solution suitable for immediate use in humans without further washing, volume reduction, or processing.
