The intestine is characterized by morphofunctional differences along the proximodistal axis. The aim of this study was to derive mesenchymal cell lines representative of the gut axis. We isolated and cloned rat intestinal subepithelial myofibroblasts raised from 8-day proximal jejunum, distal ileum, and proximal colon lamina propria. Two clonal cell lines from each level of the gut were characterized. They 1) express the specific markers vimentin, smooth muscle α-actin, and smooth muscle myosin heavy chain, revealed by immunofluorescence microscopy and 2) distinctly support endodermal cell growth in a coculture model, depending on their regional origin, and 3) the clones raised from the various proximodistal regions maintain the same pattern of morphogenetic and growth and/or differentiation factor gene expression as in vivo: hepatocyte growth and/or scatter factor and transforming growth factor-β1 mRNAs analyzed by RT-PCR were more abundant, in the colon and ileal clones and mucosal connective tissue, respectively. In addition, epimorphin mRNA studied by Northern blot was also the highest in one ileal clone, in which it was selectively upregulated by all-trans retinoic acid (RA) treatment. Epimorphin expression in isolated 8-day intestinal lamina propria was higher in the distal small intestine and proximal colon than in the proximal small intestine. In conclusion, we isolated and characterized homogeneous cell subtypes that can now be used to approach the molecular regulation of the epithelium-mesenchyme-dependent regional specificity along the gut.

The regeneration of the nervous system is a challenging task. Currently, regenerative medicine approaches that exploit nature-inspired cues are being studied and hold great promise. The possibility to use protein-based matrices functionalized with small oligo- and monosaccharides is of interest since these can be finely tuned to better mimic the native environment. Collagen has been selected as a promising material that has the potential to be further tailored to incorporate carbohydrates in order to drive cell behavior towards neuroregeneration. Indeed, the grafting of carbohydrates to collagen 2D matrices is proved to enhance its biological significance. In the present study, collagen 2D matrices were grafted with different carbohydrate epitopes, and their potential to drive F-11 neuroblastoma cells towards neuronal differentiation was evaluated. Collagen functionalized with α-glucosides was able to differentiate neuroblastoma cells into functional neurons, while sialyl α-(2→6)-galactosides stimulated cell proliferation.

The regenerative medicine space is one that is set to explode with considerable innovation and profitability for shrewd biotechnologists. I had the opportunity to speak with Michael West, PhD., CEO of BioTime (BTX) and found a man passionate about regenerative medicine and of course passionate about his role in its future. In this conversation I learned of West's vision, which I think provides some powerful clues as to areas of future growth in the biotech sector. He points to three scientific advances that make this vision actualizable. First, sequencing technology that allows us to perform RNA sequencing for around 300 dollars or less, second the common and reversible molecular basis for age-related diseases, and finally industrial scaling of pure cell lines like the ones manufactured by BTX. Let's look at the three enabling technologies that West touched on and examine how they are being utilized to achieve West's vision within BTX and others involved in the anti-aging revolution.

Many molecules have been implicated in kidney development, often based on experimental animal studies with organ cultures and cell lines. There are very few studies, however, that have directly addressed equivalent living human embryonic tissues. We generated renal mesenchymal cell lines from normal human metanephroi and used a microarray strategy to define changes in gene expression after stimulation with growth factors which enhance nephrogenesis in rodents. Changes were observed in 1) genes modulating diverse general cellular processes, such as matrix metalloproteinase 1 and stanniocalcin 1; 2) genes previously implicated in organogenesis e.g., sprouty 4 and midline 1; and 3) genes involved in blood vessel growth, including angiopoietin 1 and 4. Expression of these same genes was subsequently confirmed in vivo. Our novel data have identified several previously unhighlighted genes that may be implicated in differentiation programs within early human nephrogenesis.

In recent years several genes have linked amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) as a spectrum disease; however little is known about what triggers their onset. With the ability to generate patient specific stem cell lines from somatic cells, it is possible to model disease without the need to transfect cells with exogenous DNA. These pluripotent stem cells have opened new avenues for identification of disease phenotypes and their relation to specific molecular pathways. Thus, as never before, compounds with potential applications for regenerative medicine can be specifically tailored in patient derived cultures. In this review, we discuss how patient specific induced pluripotent stem cells (iPSCs) have been used to model ALS and FTD and the most recent drug screening targets for these diseases. We also discuss how an iPSC bank would improve the quality of the available cell lines and how it would increase knowledge about the ALS/FTD disease spectrum.
