The vitamin requirements for culture of rabbit morulae to expanded blastocysts were examined. Early morulae were cultured for 5 days either in a control complete medium containing all the 11 water-soluble vitamins of F10 culture medium (biotin, pantothenate, choline, inositol, niacinamide, pyridoxin

β¦ Synopsis
Ten amino acids, namely, arginine, histidine, lysine, tryptophane, methionine, phenylalanine, leucine, valine, threonine and serine were indispensable for growth of rabbit blastocysts i n vitro; others were nonessential. Of all the essential amino acids, arginine and lysine were required in relatively high concentrations, 10-2 M and 10-3 M, respectively, for optimum growth. Complete omission of the nonessential amino acids from the medium markedly reduced blastocyst growth. Interaction between serine and glycine demonstrated a partial sparing action on serine by glycine, similar to that observed between methionine and cysteine. The amino acid composition of a culture medium capable of providing continuous and consistent growth of rabbit blastocysts i n vitro is described.
