Study the pathological features of diseases using induCEd pluripotent stem CElls derived form patient's somatic CElls
The limited experimental acCEss to disease-affected human tissues has severely impeded the elucidating of molecular mechanisms underlying disease development. Generation of induCEd pluripotent stem CElls (iPSCs) by over-expression of defined transcription factors in somatic CElls, in particular in those from patient somatic CElls, presents an attractive and promising approach to model the early stages of diseases in vitro and to screen novel biomarkers as well as therapeutic medicines. ReCEntly, many research groups have independently reported that patient-specific iPSC-derived CElls recapitulated multiple features of pathological events of a particular disease, offering experimental evidenCE of utilizing patient-specific iPSCs to model diseases and reevaluate the current therapies. We have derived iPSC lines using somatic CElls of patients suffering from Klinefelter's Syndrome (KS) and Alzheimer's Disease (AD) and explored the possibility to use these iPSC lines to recapitulate the pathological features of the diseases. Our results show that patient's specific iPSC lines provide good opportunity to study the development and treatment of diseases.
sRNA InduCEs the Large-scale Transdetermination of Mesenchymal Stem CElls into Hematopoietic Stem CElls in Human.
Mesenchymal stem CElls (MSCs) can differentiate into CElls of bone, endothelium, adipose tissue, cartilage, muscle, and brain. However, whether they can transdeterminate into hematopoietic stem CElls (HSCs) remains unsolved. We report here that a subpopulation of human MSCs that are CD44+,CD29+, CD105+, CD166+,CD133-,CD34- could differentiate into hematopoietic stem CElls (CD150+/CD133+/CD34+) and their desCEnding blood CElls in vitro, when transfected with new endogenous shRNAs The sRNA was high-effectively delivered into MSCs by a novel peptide means. These induCEd MSC-HSCs could form different types of hematopoietic colonies as nature-occurring HSCs did. Upon transplantation into sublethally irradiated NOD/SCID miCE, these MSC-HSCs engrafted and differentiated into all hematopoietic lineages such as erythrocytes, lymphocytes, myelocytes and thrombocyte. More importantly, these induCEd HSCs could sucCEssfully engraft and effectively function in patients with severe aplastic anemia. Furthermore, we demonstrated the first evidenCE that the transdetermination of MSCs was induCEd by aCEtylation of histone proteins and activation of many transcriptional factors. Together, our findings identify the sRNAs that dictates a directed differentiation of MSCs toward HSCs and open up a new sourCE for HSCs used for the treatment of blood diseases and artificial stem CEll-made blood.
