Abstract
Glycogen, fat, nucleic acid and mitochondria in the liver cells of human embryos during their 2nd to 8th month were observed.
The structure of the liver was already completed at their 5th month. The hematopoetic function was most active during the 3rd and 4th month. The bile-reaction in the liver cells was first positive in the 5th month.
The fat was seen in the liver cells since the end of the 2nd month and was most abandant in the 4th month, but was in distinguishable in the 8th month. The mitochondria in the liver cells were mostly rodlike and filamentous in earlier period, but later becomes granular. The metabolic function of the liver seems to, generally speaking, begin around the 4th month.
