猪多能性干细胞研究进展与前瞻

Porcine Pluripotent Stem Cells :Facts,Challenges and Hopes

多能干细胞具有能够分化为多种特定细胞类型的能力,主要包括胚胎干细胞、胚胎生殖细胞和诱导多能干细胞。猪因其在免疫学、形态学和生理结构上与人有着诸多类似的特点,正逐渐成为人类异种移植、细胞治疗和再生医学研究的理想生物学模型。然而,目前对猪多能干细胞的来源、特征及机制认识的不足直接阻碍了该研究领域的发展。因此,将对猪多能性干细胞的种类、鉴定标准、研究进展、亟待解决的问题进行详细地阐述,并在此基础上对猪多能性干细胞的研究进行了展望,希望为该研究领域的科研人员提供参考。

Pluripotent stem cells, including embryonic stem cells, embryonic germ cells and induced pluripotent stem cells, have the ability to differentiate into a variety of specific cell lines. Swine is considered as a kind of ideal model for pre-clinical development of human xenotransplantation, therapeutic approaches and regenerative medicine due to its morphological and functional affinity with man. However, a number of open questions need to be addressed since we know little about the sorting, derivation, characterization and mechanisms of porcine pluripotent stem cells. In this review, we elaborated the latest progresses on the derivation of porcine pluripotent stem cells, the evaluation criteria of stemness, scientific and technique questions encountere, and we also provide our perspectives on the future study ofporcine pluripotentstem cells research, in the hope of sharing experimence of exploring this field with other researchers.
