美国Brand,null 产品货号： 7220Item#, 人前脂肪细胞-皮下<br>英文名称： Human Preadipocytes-subcutaneous

人前脂肪细胞--皮下说明：

脂肪细胞在能量储存和代谢过程中有着重要的作用。脂肪细胞分化是一个发展的过程，它对代谢稳态和营养信号很重要。它由复杂的过程控制，如基因表达和信号转导。前脂肪细胞存在于***脂肪组织中，能根据能量的平衡增殖和分化成熟的脂肪细胞。前体细胞的增殖和分化能够增加脂肪组织的体积。在体外培养中，不同的组织来源前脂肪细胞的油脂含量，成脂转录因子表达和TNFalpha诱导的凋亡均有不同。同时研究表明它还与脂肪分化以及许多生理病理过程密切相关，如脂肪代谢、能量平衡、肥胖、糖尿病、高血脂和乳癌。

人脂肪细胞-皮下提取于***下脂肪组织，原代冻存，每管含有细胞数>1×106 cells/ml，此细胞通过CD44, CD90免疫荧光染色和脂肪染色验证，经测试不含有HIV-1、HBV、HCV、支原体、细菌、酵母和真菌。

推荐培养基（PAM, Cat. No. 7211）、（PADM, Catalog No. 7221）、（AdM, Catalog No. 7201）

Sciencell公司产品由上海中乔新舟生物科技有限公司优质供应

       近几年的新药研发成功率在逐年下降，其根本原因之一就是传统的药物筛选系统是建立在只具有30-40%人类基因群的一系列细胞株上。这样一个有“缺陷型”药物筛选系统所产生的药物用于人体上就会出现许多致命的弱点和不完整性。新一代药物筛选系统是含有一系列近乎完整的人类基因群的原代细胞株。而利用这些原代细胞株所甄别和筛选出来的候选药物，其诊治人类疾病的成功几率将大大增加。这样不但大大节省了新药的开发成本，而且将极大地提高人类的健康质量。这些产品从根本上提高了全球生命医学研究、人类重要疾病药物研发、新药研发的成功率。所以上海中乔新舟生物科技有限公司致力于提供优质原代细胞产品和完善的售后服务。

       美国ScienCell研究实验室（www.sciencellonline.com）成立于1999年，公司总部位于美国加州的圣地亚哥。主要致力于实验室科研用原代细胞、原代细胞专用培养基、原代细胞无血清培养基、干细胞、干细胞培养基、干细胞无血清培养基的研究和开发，在全球拥有众多客户。在国内销售15年来，很多老师应用其产品发表了高质量的SCI文章，凭借着严格的质控和优秀的产品品质，深受广大科研工作者的信赖。

        ScienCell研究实验室生产的原代细胞、原代细胞专用培养基都经过了严格的质量控制，细胞纯度可达98％。其中包括21种人体正常细胞系统，90多种不同细胞类型。大多数细胞在全球唯有ScienCell实验室能够成功分离，产品质量过硬。确保了实验结果的真实性、重复性和连贯性。

Description

The epithelial layer of the skin provides an essential function as a protective barrier against insult from the outside environment. The major cell type in this layer is keratinocytes which consists around 85% of living epidermal cells. Keratinocytes are the cells of stratified squamous epithelia. It is so named because its most abundant protein is keratin. Keratinocyte divide and are thus generated in the basal layer of the epidermis; this division is followed by a programmed death as they produce keratin and move up to the surface of the epidermis. Keratinocyte proliferation, differentiation, and apoptosis are complex and carefully choreographed processes [1]. Besides the protective function, keratinocytes also play a central role in tissue homeostasis, wound healing, cancers, and skin-based gene-therapy. Human keratinocytes express adhesion molecules and cytokines indicating their participation in skin innate immunity and homeostasis in vivo [2, 3].

HEK-n from ScienCell Research Laboratories are isolated from neonate human epidermal tissue. HEK-n are cryopreserved on primary culture and delivered frozen. Each vial contains >5 x 10^5 cells in 1 ml volume. HEK-n are characterized by immunofluorescent method with antibodies to cytokeratine-18 and -19. HEK-n are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HEK-n are guaranteed to further expand for 15 population doublings in the condition provided by ScienCell Research Laboratories.
