Six weeks after implantation, small amount of oval lacunae appeared. PGA fibers began to be absorbed. The amount of collagen increased and Safranin O stained positively. Eight weeks after implantation, cartilage with single or occasionally double chondrocytes in round lacunae was found.

体内埋植4周后可见PGA纤维间被不成熟的软骨细胞充填。6周时出现椭圆形软骨陷窝，PGA纤维开始吸收，胶原增多，番红花—"O"有阳性染色。8周时软骨陷窝呈圆形，单个，双个对称或多个排列。

Staining results of ADSCs: The extracellular matrix Alcian blue staining, Safranin O/Fast Green staining and collagen Ⅱ immunohistochemistry were positive.

The central part was composed of hypertrophic chondrocytes, for which the number increased with time. The cartilaginous tissue at the time of 2 weeks' cultivation appeared strongly positive staining of collagen type Ⅱ immunohistochemistry and safranine "O", as well as strongly metachromatic to toluidine blue.

其中心为肥大软骨细胞，且随培养时间的延长而增多。2周时，软骨组织甲苯胺蓝染色呈强的红色异染反应，Ⅱ型胶原免疫组织化学染色呈强阳性，番红"O"染色呈强阳性。

A new parallel-epiphyseal cartilaginous tissue was found in the subcutaneous tissue 4 weeks after operation. The tissue was stained with HE, toluidine blue, safranine O and collagenⅡ. A large number of chondrocytes and a cartilage lacuna-like structure were observed under a microscope with no obvious inflammatory reaction around the calcium alginate and polylysine microspheres.
