The present invention relates to an artificial cartilage containing mesenchymal stem cell (MSC)-like dedifferentiated cells obtained by passage culturing costal chondrocytes, and a preparation process thereof.

Artificial cartilage containing chondrocytes obtained from costal cartilage and preparation process thereof

The present invention relates to a preparation method for a therapeutic agent of a bead-type chondrocyte and, more specifically, to: a preparation method for a therapeutic agent of a bead-type chondrocyte without a support, comprising the steps of: a) dispensing chondrocytes and/or cells having chondrogenic differentiation capability in a 96-well deep well plate having a V-shaped bottom; b) centrifuging the plate; c) three-dimensionally culturing the plate in an incubator; and d) recovering pellets from each well, thereby being capable of easily and stably preparing cartilage tissues of a uniform quality, in large quantities; and a therapeutic agent of a bead-type chondrocyte without a support, prepared by the method, having effectiveness to repair damage by simply being implanted into cartilage damage by injection.

Preparation method for therapeutic agent of bead-type chondrocyte

Systems, methods and computer program product embodiments for providing a locking protocol for partitioned and distributed database tables are disclosed herein. A locking method includes executing, by at least one processor, a first database transaction on a second node, attempting to acquire and acquiring a lock on the second node in intentional exclusive mode, executing, by the at least one processor, a second database transaction on a first node, acquiring a lock on the first node in exclusive mode and waiting to acquire a lock on the second node in exclusive mode, routing, by the at least one processor, the first database transaction to the first node and unsuccessfully trying to acquire a lock on the first node and committing, by the at least one processor, the first database transaction.
