HighQC™ Human Keratinocyte Stem Cells are isolated from healthy human epidermal tissue and represent a stem-like basal subpopulation essential for epidermal renewal and repair. These cells display a small, cobblestone-like or keratinocyte-like morphology and express basal keratinocyte markers such as Keratin 19, CD 34, CD 117, Nestin. They are enriched and maintained under feeder-free, serum-free conditions that preserve their proliferative potential and multipotent differentiation capacity. Their stemness is supported by the expression of integrins (e.g., α6, β1) and the absence of differentiation markers like involucrin in undifferentiated states. Each lot undergoes rigorous screening and isolation procedures, and is rigorously tested to ensure it is free of contamination from HIV-1, HBV, HCV, syphilis, mycoplasma, fungi, yeast, and bacteria.
HighQC™ Human Keratinocyte Stem Cell, Human Epidermal SC, hKeraSC, Human Keratinocyte Progenitors
HighQC™ Human Keratinocyte Stem Cells serve as an ideal model for studying epidermal development, wound healing, skin aging, and dermatological diseases such as psoriasis or squamous cell carcinoma. Their robust proliferative and differentiation potential makes them highly suitable for regenerative medicine, 3D skin equivalents, and drug toxicity testing. These cells, as skin-derived keratinocyte progenitors, also provide a valuable tool for gene editing and pathway analysis in keratinocyte biology.

优先确认水浴解冻是否在 1 – 2 分钟内完成、冻存保护剂是否已离心去除，以及培养器皿是否已按要求包被。其次检查培养基是否预温至 37 ℃、接种后 24 小时内是否移动过培养瓶。若贴壁率仍低于 70%，请提供复苏记录与显微照片，我们协助复核批次情况。
原代细胞在体外培养中会随代次增加出现形态变化，属常见现象。若在早期代次即出现明显异常，通常与接种密度过高、血清批次差异或传代消化过度有关。建议降低接种密度、统一血清批次，并在汇合度 80% 左右及时传代。
收到后请先核对冻存管外观与干冰余量，若仍有干冰可暂存 −80 ℃，并尽快转入液氮气相长期保存；若干冰已完全升华，建议直接复苏使用或按说明书转入液氮。避免在 −80 ℃ 与液氮之间反复转移，也不要在 −20 ℃ 存放细胞。
每批细胞随货提供鉴定报告，含标志物免疫荧光图像与阳性率数据。建议实验前自行复核标志物表达，如需额外标志物检测或 STR 鉴定，可在询价时说明。
提供。常规规格见产品信息表，可申请大包装；特定物种、组织来源或疾病模型来源的定制分离服务按项目评估周期与报价。请在询价表单中注明细胞类型、物种、预计用量与标志物要求。
