OBJECTIVE:

The initiation of synovial hankie to a meniscal lesion is essential for meniscal healing. Synovial Mesenchymal branch cells (MSCs) are an appealing dungeon source since of their high proliferative and chondrogenic potentials. We examined either transplantation of synovial MSCs promoted recovering after meniscal correct of extended longitudinal rip of avascular area in a microminipig model.

DESIGN:

Longitudinal rip lesion was done in middle menisci and sutured in both knees, and afterwards a synovial MSC cessation was administered for 10 min usually in uneven knee. The sutured meniscus was evaluated morphologically and biomechanically during 2, 4, and 12 weeks. The function of transplanted MSCs was also examined.

RESULTS:

The meniscal recovering during 12 weeks was significantly improved in a MSC organisation than in a control group; macroscopically, histologically and by T1rho mapping analysis. Transmission nucleus little research demonstrated that a meniscus lesion was assigned by unenlightened collagen fibrils usually in a MSC group. Biomechanical research suggested that a tensile strength to disaster of a meniscus aloft in a MSC organisation than in a control organisation in any microminipig. Synovial hankie lonesome improved along a extraneous covering from a outdoor section into a lesion of a meniscus in a MSC organisation during 2 and 4 weeks in any microminipig. Synovial MSCs labeled with ferucarbotran were rescued in a meniscus lesion and adjacent synovium by MRI during 2 weeks.

CONCLUSION:

Transplantation of synovial MSCs promoted recovering after meniscal correct with initiation of synovium into a longitudinal rip in a avascular section of meniscus in pigs.
