骨形态发生蛋白-2（BMP-2）是TGF-β超基因家族的成员，其主要生物学作用是诱导未分化的间充质细胞分化形成软骨和骨。

As a member of TGF-β supergene family, bone morphogenetic protein-2 (BMP-2) acts mainly on the induction of differentiation of undifferentiated mesenchymal cells to form cartilage and bone.

骨形态发生蛋白-2（BMP-2）是TGF-β超基因家族的成员，其主要生物学作用是诱导未分化的间充质细胞分化形成软骨和骨。

Causes: malnutrition due to pregnancy, fetal calcium deficiency, resulting in weak laryngeal cartilage, inspiratory pressure increases, so epiglottis crimp contacts on both sides of the edge inward, or too large epiglottis and soft, two aryepiglottic fold side close to each other, narrowing into a cavity valve-like tremors occur ming throat.

发病原因：可由于妊娠期营养不良，胎儿缺钙，致使喉软骨软弱，吸气时负压增大，使会厌软骨两侧边缘向内卷曲接触，或会厌软骨过大而柔软，两侧杓会厌襞互相接近，喉腔变窄成活瓣状震颤而发生喉鸣。

In addition, the present case is unique in that the bursal chondromatosis lesion deeloped in association with a large, unresoled Osgood-Schlatter lesion.

Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis.

虽然软骨损伤和疼痛的关系是讨论的焦点，这些损伤可能会导致早期发生骨性关节炎并决定了运用动员的预后。

Bone induction is an important theory in the early 20th century. Urist found that bone morphogenetic protein could promote mesenchymal cell to differentiate into osteoprogenitors and chondroblast in 1965, thence many scholars went in for the significant work in this research field.

诱导成骨是近代发展的重要理论，Urist首先提出间充质细胞在骨形态发生蛋白的作用下可向成骨和成软骨方向分化，此后国内外很多学者在该领域进行了广泛深入的探索。
