Germ cell tumors of the ovary develop from the ovarian germ cells. White bread is made using flour that has had the germ and bran removed. The processing of grains is a process that helps remove the bran and germ. Inducing differentiation of certain cells to germ cells has many applications. This provides fresh flour with the benefits of wheat germ and fiber without spoilage. It emerges and originates from the outer layer of germ cells. There are also other applications of induced differentiation of germ cells. The BMP4 signaling has been found in formation of early mesoderm and germ cells. Epigenetics is based on hereditary elements other than genes that pass into the germ cells. Teratomas belong to a class of tumors known as nonseminomatous germ cell tumor. The lineage of germ cells is called germ line. These include leukemias, most lymphomas and germ cell tumors. This can cause non-Mendelian segregation of alleles in germ cells. Gametes are produced by meiosis of a diploid germ line cell. This condition could be changed by additional feeding with wheat germ.
