类器官（Organoids）是指将成体干细胞或多能干细胞在体外三维培养形成的具有一定空间结构的组织类似物。类器官在组织结构、细胞类型、自我更新能力和功能等方面与来源组织高度一致，从而在发育生物学、疾病造模、精准医学、药物研发、基因和细胞疗法、感染和免疫以及再生医学等生物医学的多个领域展现出独特的优势。

产品介绍 Background:
Basic fibroblast growth factor (bFGF), also known as FGF2, is a member of the FGF superfamily of mitogenic proteins which show 35-60% amino acid conservation[1]. FGF acidic and basic are unique from other members of the family in that they lack classical secretory signal peptides. It is a highly specific chemotactic and mitogenic factor for many cell types, appears to be involved in remodeling damaged tissue, such as ulcer healing, vascular repair, traumatic brain injury[2]. FGF basic may play a role in vivo in the modulation of such normal processes as angiogenesis, wound healing and tissue repair, embryonic development and differentiation, and neuronal function and neural degeneration. Additionally, FGF basic may also participate in the development of several pathological conditions resulting from excessive cell proliferation and/or angiogenesis[3]. BFGF is a critical component of human embryonic stem cell culture medium[4].
