Derivation of embryonic stem (ES) cells genetically identical to a patient by
somatic cell nuclear transfer (SCNT) holds the potential to cure or alleviate
the symptoms of many degenerative diseases while circumventing concerns
regarding rejection by the host immune system.
由於不必担心自体免疫的问题
大家对利用核转移制成干细胞治疗或减缓退化性疾病有很高的期待
However, the concept has only
been achieved in the mouse, whereas inefficient reprogramming and poor
embryonic development characterizes the results obtained in primates.
可惜现在只有老鼠做得出来这种干细胞
灵长类成功的例子还没出现
Here, we used a modified SCNT approach to produce rhesus macaque blastocysts
from adult skin fibroblasts, and successfully isolated two ES cell lines from
these embryos. DNA analysis confirmed that nuclear DNA was identical to donor
somatic cells and that mitochondrial DNA originated from oocytes. Both cell
lines exhibited normal ES cell morphology, expressed key stem-cell markers,
were transcriptionally similar to control ES cells and differentiated into
multiple cell types in vitro and in vivo. Our results represent successful
nuclear reprogramming of adult somatic cells into pluripotent ES cells and
demonstrate proof-of-concept for therapeutic cloning in primates.
我们很荣幸的在这边跟大家炫耀
我们用皮肤的fibroblasts做出两株干细胞株
虽然你们一定很忌妒但是我们已经确定那是干细胞了

美国人做出来的
有钱真好
