Crosslinkable polymers, such as dendritic macromolecules and their in vitro, in vivo, and in situ uses are disclosed. These biomaterials/polymers are likely to be an effective sealant/glue for a variety of surgical procedures where the site of the wound is not easily accessible or when sutureless surgery is desirable. Crosslinkable dendritic macromolecules can be fabricated into cell scaffold/gel/matrix of specified shapes and sizes using chemical techniques. The polymers, after being crosslinked, can be seeded with cells and then used to repair or replace organs, tissue, or bones. Alternatively, the polymers and cells can be mixed and then injected into the in vivo site and crosslinked in situ for organ, tissue, or bone repair or replacement. The crosslinked polymers provide three dimensional templates for new cell growth that is suitable for a variety of reconstructive procedures, including custom molding of cell implants to reconstruct three dimensional tissue defects. The crosslinked gel can also be used as an endocapsular lens.
本文披露了可交联聚合物,如树状大分子及其在体外、体内和原位的使用。这些生物材料/聚合物很可能成为一种有效的封闭剂/胶水,用于各种手术程序,其中伤口部位不易接近或需要无缝缝合的情况。可交联的树状大分子可以使用化学技术制成指定形状和大小的细胞支架/凝胶/基质。聚合物交联后,可以播种细胞,然后用于修复或替换器官、组织或骨骼。或者,聚合物和细胞可以混合,然后注入体内部位并在原位交联,用于器官、组织或骨骼的修复或替换。交联的聚合物为新细胞生长提供了三维模板,适用于各种重建手术,包括定制细胞植入物以重建三维组织缺陷。交联凝胶还可以用作内囊晶体。
