"A complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. In Deuterostomes the initial blastopore becomes the anus and the mouth forms second [goid 1702] [evidence IEA]; The process of introducing a phosphate group on to a protein [goid 6468] [evidence IEA]; The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis [goid 7283] [evidence IEA]; The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry [goid 7368] [evidence IEA]; The process whose specific outcome is the progression of the mesoderm over time, from its formation to the mature structure. The mesoderm is the middle germ layer that develops into muscle, bone, cartilage, blood and connective tissue [goid 7498] [evidence IEA]; The regionalization process by which specific areas of cell differentiation are determined along the anterior-posterior axis [goid 9952] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of bone mineralization [goid 30501] [pmid 18436533] [evidence IMP]; A series of molecular signals generated as a consequence of any member of the BMP (bone morphogenetic protein) family binding to a cell surface receptor [goid 30509] [pmid 15621726] [evidence EXP]; A series of molecular signals generated as a consequence of any member of the BMP (bone morphogenetic protein) family binding to a cell surface receptor [goid 30509] [pmid 18436533] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of the activity of any activin receptor signaling pathway [goid 32927] [pmid 12665502] [evidence IDA]; The expulsion of seminal fluid, thick white fluid containing spermatozoa, from the male genital tract [goid 42713] [evidence IEA]; The hardening, enlarging and rising of the penis which often occurs in the sexually aroused male and enables sexual intercourse. Achieved by increased inflow of blood into the vessels of erectile tissue, and decreased outflow [goid 43084] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of erythrocyte differentiation [goid 45648] [pmid 9032295] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of osteoblast differentiation [goid 45669] [pmid 18436533] [evidence IMP]; The process, occurring during the embryonic phase, whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure [goid 48706] [evidence IEA]; Any process that modulates the activity of the enzyme nitric-oxide synthase [goid 50999] [evidence IEA]; The multiplication or reproduction of Sertoli cells, resulting in the expansion of the Sertoli cell population. A Sertoli cell is a supporting cell projecting inward from the basement membrane of seminiferous tubules [goid 60011] [evidence IEA]"
