Research Interests or Current Research Focus
Dr. Jin’s group is interested in:
1) identification and investigation of critical signaling pathways and intrinsic factors controlling the cell fate determination of pluripotent cells;
2) the molecular mechanisms underlying somatic reprogramming and modeling disease using disease iPS cell lines;
3) understanding how early neural differentiation is induced in human pluripotent stem cells.

Major Research Achievement
The grouphas established 7 human ESC lines, including 3 lines generated under a xeno-free condition. Of these cell lines, SHhES1 and SHhES2were used in a global study organized by the International Stem Cell Initiative and related data were published in Nature Biotechnology 2011. Recently, they also generated induced pluripotent stem cells (iPSCs) from mouse and human somatic cells. In particular, they derived human iPSC lines using fetal cells from amniotic fluid efficiently. Moreover, they established human iPSC lines using patients’ samples. With these pluripotent cell lines, the group has set up a robust neural differentiation protocol, which will be used to explore the regulation of transition from pluripotent state into the neural epithelium.
Self-renewal and pluripotency are hallmarks of embryonic stem cells (ESCs). However, the signaling pathways that trigger their transition from self-renewal to differentiation remain elusive. They identify that calcineurin-NFAT signaling is both necessary and sufficient to switch ESCs from an undifferentiated state to lineage-specific cells and that the inhibition of this pathway can maintain long-term ESC self-renewal independent of leukemia inhibitory factor. The results demonstrate that the NFAT and Erk1/2 cascades form a signaling switch for early lineage segregation in mouse ESCs.
To explore the genetic basis of human early embryonic development, Dr. Jin’s group we used microarray to detect and analyze gene expression of the post-implantation human embryos at six successive developmental stages from Carnegie stage 9 to 14, spanning the period from the onset of organogenesis to formation of primordia of the most organs. The study provides us a great amount of information of temporal and genome-wide gene expression patterns of human embryo development.
The group has made great efforts to elucidate the regulatory mechanism of key transcription factor Oct4-centered core transcriptional circuitry for ES cell fate decision. Their studies 1) identify the posttranslational ubiquitin and SUMO modification of Oct4 by Wwp2 and Ubc9;2) reveal that PARP1 can Poly(ADP-ribosyl)ate Sox2 to control Sox2 protein levels and FGF4 expression during ES cell differentiation;3) uncover critical roles of coactivator p300 in mouse ES cell differentiation and nanog expression;4) identify a new Oct4 target gene, Stk40, which links the pluripotency factor Oct4 to the Erk/ MAPK pathway; 5) report the important roles of nucleolar proteins for controlling self-renewal and differentiation in ES cells.
