Mammalian placentae exhibit wide structural diversity among different species and are formed under intricate interplay between the embryonic trophoblast and the maternal endometrial cells. Increasing evidence in the literature indicates a possible role played by homeobox genes in the complex placental organogenesis. Although the expression of all HOX 9 paralogs has been demonstrated both in highly invasive murine hemochorial placentae and in non-invasive caprine synepitheliochorial placentae, no reports so far published in the literature described the patterns of gene expression of Hoxc-9 in the murine nor those of HOXC-9 in the caprine placenta at cellular levels. We carried out comparative analyses of the location and identity of the cells expressing Hoxc-9/HOXC-9 during various stages of placentation in the murine hemochorial and caprine synepitheliochorial placentae by means of in situ hybridization using murine Hoxc-9 or caprine HOXC-9 cRNA probe, respectively. The results demonstrated that Hoxc-9 mRNA was expressed at high levels in giant trophoblast cells of murine placentae on Days 12-19, but not on Day 8. Similar analysis of caprine Day 75 and Day 100 placentae revealed that the binucleate trophoblast cells that penetrate the uterine luminal epithelial cell layer, strongly expressed HOXC-9 mRNA. Although the functional significance of Hoxc-9/HOXC-9 gene expression in trophoblast cells remains to be elucidated, it was suggested that it might play a role in the regulation of invasiveness or endocrine activities in the murine giant trophoblast cells and/or the caprine binucleate trophoblast cells.

The family of paired-related homeobox genes to which Prx1 and Prx2 belong plays an integral role in limb and craniofacial development, as evidenced by both transgenic mice and in situ hybridization data. However, little is known about protein expression of these homeodomain transcription factors. Recent studies in our lab have established the pattern of Prx1 protein expression during normal mouse embryogenesis. Here we present a comparative analysis of Prx1 and Prx2 protein expression in the developing mouse using a novel anti-Prx2 antibody reagent.

The Turner syndrome (TS) is a complex disorder associated with almost invariant short stature and gonadal dysgenesis, as well as a variety of other major organ malformations. Recently, a homeobox-containing gene entitled short-stature homeobox-containing gene (SHOX), was isolated from a minimal short stature gene interval from the pseudoautosomal region of Xp (and Yp). Together with the demonstrable escape of SHOX from X-inactivation, this suggested SHOX to be a strong candidate gene for the short stature component of TS, and as SHOX haploinsufficiency appears to be the molecular basis of a mesomelic short statured skeletal dysplasia (Leri-Weill syndrome), this suggested that SHOX protein expression levels may confer a dosage effect on human stature. However, in this communication we report a normal statured female with gonadal dysgenesis, due to the inheritance of a recombinant duplication-deletion X-chromosome. The karyotype of the proband was 46,X,rec(X)dup(Xp)inv(X)(p11.22q21.2)mat and fluorescent in situ hybridization of her metaphases with a SHOX cosmid confirmed the proband to be trisomic for SHOX. This communication suggests the relationship between levels of SHOX expression and human stature to be more complex than envisaged previously. The presence of normal stature in our patient rather than tall stature is likely to represent the natural variation seen in patients with transcription factor disorders.

We characterize the urorectal septum malformation sequence (URSMS) in discordant fetal lambs and relate it to the human syndromes with which URSMS is associated. We found abnormal external genitalia, imperforate anus, and fistulous connections between the rectum, bladder, and vagina. Discordance among the dizygous twins eliminated teratogens as a likely etiologic factor. We summarize the relevant literature and propose a molecular model for the pathogenesis of the URSMS, in which alterations in sonic hedgehog and homeobox genes lead to caudal mesodermal deficiency during blastogenesis.

Recently, two orthologues of the Drosophila homeobox Cut gene, Cux-1 and Cux-2, have been identified as restricted molecular markers of upper layer (II-IV) neurons in the murine cerebral cortex. We show that during early postnatal life, from P0 to P10, Cux-1 and Cux-2 mRNA are coexpressed in all primary sensory cortices. Antisera to Cux-1 and Cux-2 immunoreactivities preferentially label neurons in the barrel walls of the primary somatosensory cortex (S1). Subsequently, Cux-1 remains enriched in sensory cortices, whereas Cux-2 expression enlarges to comprise the frontal and insular areas. The laminar distribution of Cux-1 and Cux-2 differs: Cux-1 follows a layer IV to layer II decreasing gradient of expression, whereas Cux-2 expression is homogeneous across layers IV-II. No colocalization was found with GABA and birth dating experiments showed that Cux-1-positive neurons in layer IV are born during a restricted period, E13.5-E14.5, suggesting that Cux-1 is a useful molecular marker of the glutamatergic neurons of layer IV. We examined Cux-1 and Cux-2 in barrel-defective mouse strains, the VMAT2 KO, the MAOA KO, and the Adcyl 1(brl) strain. A normal expression level of Cux-1 and Cux-2 was found in layer IV, despite the lack of segregation of the neurons as barrels. Conversely, in Reeler mice, Cux-1 and Cux-2 had a distinct laminar distribution: the Cux-1-positive neurons had an inverted deep localization, whereas the Cux-2-positive neurons were distributed throughout the cortical thickness, suggesting that Cux-2 expression is more widely expressed in the inverted cortex of reeler mutants. Our results indicate that Cux-1 is a useful marker of the layer IV neurons in S1, and that Cux-1 and Cux-2 are differently regulated in the upper layers of the cerebral cortex.

Islet cell transplantation is one of the most promising therapies for diabetes mellitus (DM). However, the limited availability of purified islets for transplantation and the risk of immunological rejection severely limit its use. In vitro transdifferentiation of autologous bone marrow-derived mesenchymal stem cells (BMSCs) into insulin-producing cells (IPCs) could provide an abundant source of cells for this procedure and avoid immunological rejection. Here, we isolated and characterized BMSCs and induced their in vitro differentiation into IPCs. Reverse-transcription polymerase chain reaction analysis revealed that these IPCs could express Ins1, Ins2, glucagon, glucose transporter 2, and pancreatic duodenal homeobox-1. Insulin production by the IPCs was confirmed by immunocytochemistry and Western blot analysis. On this basis, donor rats supplying BMSCs were made diabetic by a single intraperitoneal injection of streptozotocin. The IPCs were then autologously transplanted into the duodenal submucosa of diabetic rats. Grafted cells could be visualized in sections after 2, 4, and 8 weeks by immunohistochemical staining for insulin. Furthermore, in the IPC-implanted group, hyperglycemia was normalized, compared with a persistent increase in glucose levels in the diabetic group and intraperitoneal glucose tolerance test-induced responses were observed in the IPC-implanted group. These results on autologous transplantation of IPCs derived from BMSCs into the duodenal wall could offer a novel potential therapeutical protocol for DM.
