Unveiling the Intricate Development of Human Limbs: From Embryonic Atlas to Nature's Chiseling
Originally Published 2 years ago — by Nature.com
Researchers have created a comprehensive atlas of human embryonic limb development using single-cell transcriptomic RNA sequencing and spatial transcriptomic sequencing. The study identified 67 distinct cell clusters and mapped their spatial distribution across four timepoints during the first trimester of development. The research sheds light on the cellular heterogeneity, patterning events, and gene expression patterns associated with limb malformations. The findings also highlight the similarities between human limb development and that of model organisms like mice. This atlas provides valuable insights into the complex processes involved in limb development and can serve as a reference for studying genetic variations and developmental disorders.
