Microscopic morphology of SSCs derived from neonatal male mice (five mice at a time in each group). Each type of experiment has three replicates. The sizes of the colonies are shown at the end of the second week (a, c) and the end of the fourth week (b, d) of SACS, as well as being positive for alkaline phosphatase activity (e). After cultivation of SSCs, the diameter and number of colonies increased in both groups, particularly in the experimental (melatonin) group. All the tests performed at least five times
