Lineage transition in adenocarcinoma (ADC) and squamous cell carcinoma (SCC) of non-small cell lung cancer, as implicated by clinical observation of mixed ADC and SCC pathologies in adenosquamous cell carcinoma, remains a fundamental yet unsolved question. Here we provide in vivo evidence showing the transdifferentiation of lung cancer from ADC to SCC in mice: Lkb1-deficient lung ADC progressiv...
After debridement of the entire corneal epithelium with n-heptanol, two groups of rabbit corneas were segregated according to the extent of corneal neovascularization. Using a new topographic goblet-cell counting method and routine histology, the authors have reexamined the process of conjunctival transdifferentiation and compared the changes of goblet-cell density and morphology between nonvas...
Mononucleated striated muscle of an anthomedusa can be isolated and cultivated in artificial sea water. When treated with bacterial coUagenase the isolated muscle can transdifferentiate autonomously into several cell types and regenerate the entire sexual and feeding organ of the medusa, the manubrium. Whereas transdifferentiation from striated to smooth muscle is direct, formation of a glandul...
Transdifferentiation, where differentiated cells are reprogrammed into another lineage without going through an intermediate proliferative stem cell-like stage, is the next frontier of regenerative medicine. Wernig et al. first described the direct conversion of fibroblasts into functional induced neuronal cells (iNs). Subsequent reports of transdifferentiation into clinically relevant neuronal...
Though in the past believed to be a rare phenomenon, endothelial-mesenchymal transdifferentiation has been described with increasing frequency in recent years. It is believed to be important in embryonic vascular development, yet less is known regarding its role in the adult vasculature. Using FACS and immunomagnetic (Dynabeads) purification techniques (based on uptake of DiI-acetylated low-den...
Developmentally, the pancreas and liver are closely related and pathological conditions - including elevated glucocorticoid levels - result in the appearance of hepatocytes in the pancreas. The role of the WNT signalling pathway in this process has been examined in the model transdifferentiating pancreatic acinar AR42J-B-13 (B-13) cell. Glucocorticoid treatment resulted in a transient loss of c...
Recent months have seen rapid advances in the field of transdifferentiation, specifically in the conversion of fibroblasts to neurons. Most surprising is the observation that the ability to drive these transitions is not limited to transcription factors, but that they can be promoted by microRNAs as well. Indeed, in one case, microRNAs alone induced the transdifferentiation of fibroblasts to ne...
Over the last few years, evidence has accumulated revealing the unexpected potential of committed mammalian cells to convert to a different phenotype via a process called transdifferentiation or adult cell reprogramming. These findings may have major practical implications because this process may facilitate the generation of functional autologous tissues that can be used for replacing malfunct...
In recent years transdifferentiation technology has enabled direct conversion of human fibroblasts to become a valuable, abundant and accessible cell source for patient-specific induced cell generation in biomedical research. The majority of transdifferentiation approaches rely upon viral gene delivery which due to random integration with the host genome can cause genome instability and tumorig...
