Project description:interdigital cell death (ICD) is an essential role in amniotes to promote the regression of interdigital tissue for digits separation. Antagonizing this process can lead to the formation of webbed limbs. However, the mechanism of forming webbed limbs is not the same among independently evolved species, and the reason is still unclear. The Chinese softshell turtle (Pelotiscus sinensis) is a good research model, exhibiting a transitional feature from no webbed to fully webbed. In this study, we collected 8 samples of interdigital webbing from the forelimbs and hindlimbs of turtles at embryonic stage 19 (TK19) for RNA sequencing. We identified 608 potential regulatory genes through differential expression analysis. These findings not only provide new perspectives and data support for comparative studies of adaptive convergent evolution in aquatic animals, but also enhance our understanding of the mechanisms underlying quadrupedal limb morphology. In addition, these results provide potential molecular targets for studying the plasticity of programmed cell death or aging.
Project description:Although macrophage-epithelioid cell (EPC)-giant cell (GC) differentiation is acknowledged in foreign body reaction (FBR), the exact molecular features remain elusive. To discover the molecular profiles of EPC and GC, we analyzed mouse sponge and silk FBRs by integrating single-cell RNA-sequencing (scRNA-seq) and spatial sequencing.
