Paper electrophoretic studies on the relationship between the free amino acid content and regeneration in planaria, 1965

Murry, Ellen S.

1960-1969

A comparison of the regenerative activity and the amino acid content was made on 4 transverse sections of planaria, designated as Sections I, II, III and IV. Transactions were made of 100 animals and these were allowed to regenerate. The amount of regeneration of each section, time involved, and number of abnormal head regenerates were observed with a small stereoscopic microscope. Thirty additional animals were transected and samples from these were analyzed for amino acid content by paper electrophoresis. Regeneration proceeded at a faster rate in Section I and there was a larger number of free amino acids in this Section. There was a much larger number of abnormal regenerates in Section III than in the other sections. This section contained only 4 amino acids. The free amino acids present in all the sections were lysine, arginine, histidine, glycine, alanine, leucine, phenylalanine, tyrosine, tryptophane, glutamic acid, aspartic acid and cystine. Experimental data seem to suggest a relationship between regenerative activity and amino acid content in 4 transverse sections of planaria.
