The results indicated that stable emulsions and macroporous structure were prepared by PELA, but hydrophobic poly and poly(lactide-co-glycolide) could only produce microcapsules.

大孔微球是一种具有网状大孔结构的新型基质，它不仅是动物细胞大规模培养[1]的关键，而且还可以应用于医

Methods:(1) bFGF was loaded with PLGA, PELA and gelatin microspheres. The pharmac characteristics of particle size distribution, loading efficiency, entrapment efficiency, bFGF release kinetics were evaluated with scanning electronic microscope, MTT and ELISA respectively.

目的：制备bFGF缓释微球并作处方筛选，在体外培养的软骨细胞中观察其促有丝分裂作用和促基质合成作用，以及在兔膝关节全层软骨缺损模型中验证其促进软骨修复的作用，为其临床应用提供实验基础。

These formulations are prepared by some macromolecule materials such as PLGA,PLA,PLG and PELA,which include microsphere,microcapsule,microemulsion,nanocapsule and nanosphere,used as carrier of delivery antigen and adjuvant.

The bioactivity of bFGF released from PLGA microspheres are higher than from PELA.(2) the bFGF released from PLGA microspheres can stimulate mitosis, proliferation, and matrix synthesis of chondrocyte more effectively than free bFGF. 10 days later after the administration of PLGA microspheres, the effects of stimulus to synthesis of type Ⅱ collagen and proteoglycan can be compared with continue administration of free bFGF.

游离bFGF对软骨细胞的促有丝分裂的作用效应期短；bFGF缓释微球能通过持续释放活性bFGF，在较长时期内促进软骨细胞的分裂增殖；Ⅱ型胶原免疫荧光测定和蛋白多糖阿新兰染色测定显示，应用微球10天后，能有效的促进软骨基质成分的合成，其效果与持续应用游离bFGF的效果相当。
