    The progressive differentiation and mapping of distinct cell lineages from a common primordium involves a series of developmental decisions and inductive interactions during organogenesis. The phenotype development of the cell lineages occur as the result of a complex synergistic or competitive regulation among numerous factors inducing or inhibiting the expression of genes. The purpose of this long-term investigating is to charaterize the ontogenetic mechanisms of cell phenotypes, patterning responsiveness to signal and molecular clock regulation in vivo embryo development or in vitro tissue culture.
    The neuron, endocrine, immune and circulatory cells are specificated cell patterns derived from ectoderm, endoderm and mesoderm of animal embryo. Among these cells have specific receptors for cell communicating and signal transduction. The cells are organized in spatiotemporal pattern of developing which regulated by secretory rhythm of signals and genomic program expression of genes. The developing patterns of main, collateral channels (Chinese Traditional Medicine) are the cross signaling through the immune, neuro-endocrine systems, and take active roles in the psychsomatic regulation of morphogenesis.

The molecular synthesis between degradation, and cell prolification between apotosis are controlled by neuro-endocrine signaling and gene expression. On the cascades of interacting regulatory in gene expression, the commitment factors, transcription factors which mediate the phenotypic expression of different cell types, receptors, intercellular signals and cell-adhesion molecules, they act on some cells very early and during a limited period of time. The major groups of transcription factors have been classified according to the motif in the DNA-binding domains. Interestingly, many transcription factors activate or repress their own expression and thus constitute the autoregulatory feedback loops which function as molecular clock. These factors regulate the cell cycle and cell specifical fate determination in morphogenesis of organism. In oocyte, cellular factors can reboot somatic nuclei genetic reprogram and maintain ES cell in totipotent.
An efficient approach, termed sequence tagged fragments display (STFD), be developed that allow for the identification of genes from differential expression tissues. Genes origined in the patterns of genes families, and proteins in structure types. There are many sequence tagged sites on the genes map. These known sequence or conserved sequence sites can be used for cloning and analysis of genes by transgenic tagging and ploymerase chain reaction (PCR). The transgenic system includes recipient cell, vector, gene transfer and embryo manipulation. In the natural and artificial evolution of organisim, the transgenesis, genetic crossover, mobile element transposon have deleterious effects and transmission unstability of genome during the coadaption of genes.
The mutagenesis and expression of gene has great potential improving the studying of the regulation of multiple signals in the developing of cell fate determination and the genetic patterns of morphogenesis. The goal of the project is useing transgenic animal models, gene transfection or mutagenesis, stem cells differentiation in vitro to chracterize the genes and signal transduction pathways involoved in the regulation of cell proliferation, differentiation, apoptosis and organogenesis.
