title: A small issue addressed.
abstract: Cell size is an important determinant of body size. While the genetic mechanisms of cell size regulation have been well studied in yeast, this process has only recently been addressed in multicellular organisms. One recent report by Wang et al. (2002) shows that in the nematode C. elegans, the TGFbeta-like pathway acts in the hypodermis to regulate cell size and consequently body size.1 This finding is an exciting step in discovering the molecular mechanisms that control cell and body size.
