Perhaps Surprisingly, The Human Brain has not Brain Cell Types that are speely us. We use The Same Collection of Cell Types As a Rodent. Using Single-Cell Rna-Sequencing, Scientists Have Now Shown That, In The Mouse Brain, There are at least 49 Cell Types. Certain Proteins in Mice, for Instance, Are Almost Identical to Proteins Found in the Human Body. The Authors of the Recent Study Wondered Whether This Same Rule Might Also Be True for Cell Types.
