- Description
- Description: The monoclonal antibody ICDCLS recognizes human, mouse, and rat Somatostatin. Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or somatotrophin release-inhibiting factor (SRIF), is a peptide hormone with two active forms (14 and 28 amino acids) produced by alternative cleavage of a single preproprotein. Somatostatin is secreted by the delta cells of the islet of Langerhans in the pancreas as well as by the hypothalamus and intestine. Somatostatin has a variety of functions, such as regulating the endocrine system and affecting neurotransmission and cell proliferation. Somatostatin also inhibits the release of numerous secondary hormones, such as insulin and glucagon. Somatostatin can be used to identify medium size aspiny neurons in the striatum, cortex, and hippocampus. Expression of somatostatin is present in hyperplasia of the pancreatic islets as well as islet cell tumors such as somatostatinomas.

- Figure 2 DBP Alters alpha Cell and delta Cell Number and Size (A and B) Cell resolution reconstruction of pancreatic sections reveals no differences in alpha cell and beta cell mass in DBP +/+ and DBP -/- mice (A), quantified in bar graph (B) (scale bar represents 530 mum; representative images are shown; inset is a zoom showing maintenance of cellular resolution in a single image; n = 9-12 sections from 3 to 4 animals; unpaired t test). (C-I) Morphological analyses of DBP -/- islets (C) reveal increased alpha cell number (D) and decreased alpha cell size (E) (representative images shown in right panel), but normal area occupied (F). By contrast, beta cell number is increased (G), although beta cell size (H) (representative images shown in right panel) and area (I) are unchanged (scale bar in D represents 85 mum; scale bars in E and H represent 10 mum; n = 24-45 islets from 3 to 4 animals; E and H are zooms of C to better show alpha cell and beta cell size; DAPI is shown in blue; unpaired t test). (J-M) delta cell proportion (J and K; n = 55-79 islets from 4 to 5 animals) and size (L and M; n = 29 to 30 islets from 3 animals) are decreased in DBP -/- islets (scale bar in J represents 85 mum; scale bar in L represents 10 mum; representative images are shown; L is a zoom of J to better show delta cell size; unpaired t test). (N) Expression levels of the alpha cell differentiation markers Arx , Pax6 , Pou3f4 , and Irx2 are similar in DBP +/- and DBP -/- islets (n = 3-10 animals;
