ABSTRACT
BACKGROUND:
Insulin-like growth factor 1 is the key factor during cartilage development, which is involved in the growth and reconstruction of condylar cartilage.OBJECTIVE:
To study the effect of insulin-like growth factor 1 on cel apoptosis and the apopotosis-associated factors of Bcl-2, Bax mRNA and protein expressions of rat condylar chondrocytes.METHODS:
The 1-day-old and 28-day-old rat condylar chondrocytes were cultured and identified in vitro. The condylar chondrocytes with different ages were divided into experimental group and control group. After being starved for 24 hours, chondrocytes in the experimental group were incubated with 100μg/L recombined rat insulin-like growth factor 1 for 48 hours, while the chondrocytes in the control group were incubated normal y. RESULTS ANDCONCLUSION:
Compared with the control group, after being incubated with recombined insulin-like growth factor 1, the number of condylar chondrocytes was increased with high speed proliferation (Pproliferation and reduce cel apoptosis of newborn and adolescent rat condylar chondrocytes, which may be mediated by Bcl-2 and Bax.
