Spermatogenic immunoglobulin superfamily (SgIGSF) is a mouse protein belonging to the immunoglobulin superfamily expressed in the spermatogenic cells of seminiferous tubules. We produced a specific polyclonal antibody against SgIGSF. Western blot analysis of the testes from postnatal developing mice using this antibody demonstrated multiple immunopositive(More)
An attempt to learn whether chemically specific neurons affect the sequence of cerebellar development was made by transplanting ectopic tissues rich in monoamines adjacent to the early developing cerebellum of neonatal rat. Three types of brainstem grafts were used: (1) ventral midline raphe region, (2) inferior olivary region, (3) locus coeruleus region.(More)
In the rat pineal organ numerous stellate cells exhibited intense immunoreactivity for calcium-binding spot 35 protein. Because of their peculiar shape and ultrastructure, identical to those of intrapineal S-100-immunoreactive cells, the spot 35-immunoreactive stellate cells were identified as the interstitial cells. The comparison of the morphology and(More)
We investigated a unique microzone of the cerebellum located in folium-p (fp) of rabbit flocculus. In fp, Purkinje cells were potently excited by stimulation of the hypothalamus or mesencephalic periaqueductal gray, which induced defense reactions. Using multiple neuroscience techniques, we determined that this excitation was mediated via beaded axons of(More)
Creativity has been proposed to be either the result of solely right hemisphere processes or of interhemispheric interactions. Little information is available, however, concerning the neuronal foundations of creativity. In this study, we introduced a new artistic task, designing a new tool (a pen), which let us quantitatively evaluate creativity by three(More)
A time course study with enkephalin(Enk)-like immunoreactivity has revealed that nerve fibers intensely immunoreactive for Enk-8 appeared transiently only during the postnatal week 2 and 4 within the acini as well as in the inter- and intralobular connective tissues of the submandibular gland of rats. At these stages numerous nerve fibers immunoreactive for(More)
Activation of peroxisome proliferator-activated receptor (PPAR)-gamma induces terminal differentiation and growth inhibition associated with G1 cell cycle arrest in some cancer cells. The multifunctional molecule beta-catenin performs important roles in intercellular adhesion and signal transduction. However, no report has focused on actions of PPAR-gamma(More)
In the submandibular gland (SMG) of mice, a duct portion called the granular convoluted tubule (GCT) is developed preferentially in males with puberty. This sexual dimorphism is androgen-dependent, but the underlying molecular mechanisms are unclear. We have demonstrated that the expression of a transcription factor JunD is regulated in association with the(More)
The 25-kDa heat-shock protein (Hsp25) is expressed in the cartilage of the growth plate and suggested to function in chondrocyte differentiation and degeneration. Using immunohistochemistry, we examined the temporal and spatial occurrence of Hsp25 in Meckel's cartilage in embryonic mice mandibles, and in other types of cartilage in both embryonic and adult(More)
We studied the expression and localization of JunD, a component of the transcription factor activator protein-1 (AP-1), in the mouse submandibular gland with immunoblotting and immunohistochemistry. In adult mice, all seven Jun and Fos family members constituting the AP-1 complex were expressed more abundantly in the female gland than in the male gland, and(More)
