Studies on the prolactin-like substance in human placenta. IV.
In the previous papers (Ito and Higashi, 1961; Higashi, 1961), it was reported that a protein which stimulates the increase of the number and size of the fatty granules in the crop milk of pigeons was obtained from human placenta by the fractional precipitation with ammonium sulfate. The present communication describes the procedure of purification of this biologically active substance and some...
متن کاملHuman placenta: de visu demonstration of interstitial Cajal-like cells
Traditional interstitial cells of Cajal (ICC) are present in the digestive tube and are supposed to act as pacemakers and neuromodulators. However, interstitial Cajal-like cells (ICLCs) were found outside the gastrointestinal tract, in various organs (e.g. ureter, bladder, fallopian tube, uterus, pancreas, mammary gland, myocardium etc.) and looking for such ICLC is a priority in our laboratori...
متن کاملThe isolation of adrenal-like steroids from the human placenta.
In previous studies on the isolation of progesterone from placenta, the presence of steroids altered by the NaOH procedure was suspected (1). This was apparently confirmed in the isolation of progesterone from pooled plasma of pregnant women by the presence of progestationally active material other than progesterone when measured by the Hooker-Forbes bioassay (2). A new analysis of placenta was...
متن کاملSecretion of pituitary-like peptides by the human placenta.
STRUCTURE Ascheim and Zondek (1927) first demonstrated the presence of gonadotrophic substances in the urine of pregnant women. Such urine injected into infantile mice induced premature oestrus with follicle ripening and luteinisation. hCG is a glycoprotein structurally related to the pituitary hormones TSH, FSH, and LH and comprises two subunits (Reichert et al., 1970; Pierce and Liao, 1970). ...
متن کاملExpression of new members of the prolactin growth hormone gene family in bovine placenta. Isolation and characterization of two prolactin-like cDNA clones.
Two prolactin-like proteins (bPLP-I and bPLP-II) were deduced from the nucleotide sequence analyses of the cDNA clones derived from a bovine (Bos taurus) term placenta. These proteins resembled bovine prolactin but were different from the reported bovine placental lactogens or prolactin-related proteins. The predicted amino acid sequences of these clones showed 45-51% identity with bovine prola...
