Abstract

The invention provides a screening method for IncRNAs which are in differential expression during chondrogenic differentiation of ADSCs, ADSCs with high cartilage differentiation capacity, and an induced differentiation method for cartilage cells. The screening method for IncRNAs comprises the following steps: gradient induced differentiation of ADSCs chondroblasts, IncRNAs sequencing of ADSCs, and analysis of IncRNAs sequencing results. The IncRNAs included in the ADSCs comprise at least one selected from the group consisting of H19, Scube3 and NONRATG00281. The ADSCs with high cartilage differentiation capacity are modified by the IncRNAs in differential expression.

Description

technical field [0001] The invention belongs to the field of biotechnology, and specifically relates to a lncRNAs screening method, lncRNAs contained in differentially expressed ADSCs, ADSCs with high cartilage differentiation ability, and a method for inducing differentiation of chondrocytes. Background technique [0002] Injuries and lesions of articular cartilage are common clinical diseases that can occur in any age and gender. Because articular cartilage lacks vascular system, lymphatic system and innervation, and does not contain progenitor cells, and chondrocytes are surrounded by dense cell matrix, the self-repair ability of the tissue is very poor after injury, and once the injury occurs, it will cause joint swelling and pain , to accelerate the progression of osteoarthritis. [0003] At present, clinical methods for repairing articular cartilage damage mainly include articular surface reconstruction methods such as cartilage debridement plastic surgery, subchondra...
