Summary : Stromal cells are connective tissue cells of any organ, and they support the function of the parenchymal cells of that particular organ. Stromal/stromal stem cells are fundamentally a heterogeneous population of cells with contradictory differentiation potential depending upon their environmental niche. Stromal cell biology is not only intriguing, but equally stromal cell ontogeny in vivo remains challenging. In recent years there has been substantial advances in our understanding of stromal cell biology, especially stromal cell isolation, characterization, differentiation, and interactions in physiological (epithelial-stromal interactions) as well as pathophysiological (stromal-cancer interactions) contexts. In addition, stromal cells are also utilized more and more as a therapeutic tool not only in the field of gene therapy but also in the translational field of tissue engineering and regenerative medicine. Therefore, the goal of this book is to consolidate the recent advances in the area of stromal/stromal stem cell biology covering a broad range of interrelated topics in a timely fashion and to disseminate that knowledge in a lucid way to a greater scientific audience. This book will prove highly useful for students, researchers, and clinicians in stem cell biology, developmental biology, cancer biology, pathology, oncology, as well as tissue engineering and regenerative medicine. This quick reference will benefit anyone desiring a thorough overview of stromal cell structure, function, and its therapeutic implications.

Summary : Cancer is a devastating disease that claims the lives of countless people due to its uncontrolled growth pattern. Among various cancers, pancreatic cancer is one of the most lethal cancers due to its aggressive nature, lack of early symptoms and resistance to chemotherapy. The molecular profile of this deadly malignancy is not completely understood. Malignancy arises due to loss or gain of function in genes involved in cell cycle progression leading to disruption of tightly regulated transitions. In addition the evolving concept of cancer throws light on a small population of cells within the tumor known as the cancer stem cells (CSCs) or tumor-initiating cells that are resistant to all drugs treatment and contributes towards tumor initiation and recurrence. Several studies have been carried out to identify specific markers for the cancer stem cell population including that of pancreatic cancer. Pancreatic Differentiation 2 (PD2) or human Polymerase Associated Factor 1 (hPaf1) is an important component of the multifunctional PAF1 complex initially identified to play a crucial role in transcriptional elongation of genes. During the last decade, several papers on PD2 showed that it is a multifaceted molecule playing roles in cell cycle regulation, stem cell maintenance, histone methylation, chromatin remodeling and acinar-to-ductal metaplasia. In this dissertation, the first goal was to investigate the role of PD2 in pancreatic cancer stem cells. Initially, we analyzed the expression and function of PD2 in pancreatic cancer stem cells isolated from pancreatic cancer cell lines, Kras (G12D); Pdx1 (Cre)(KC), Kras (G12D); Trp53 (R172H/+.); Pdx1(Cre) (KPC) mouse models and human pancreatic tumors. Furthermore, the expression of PD2 was significantly higher in CSCs isolated from pancreatic cancer cells along with CSC markers. These cells were shown to exhibit a cobblestone appearance, increased tumorsphere formation and significant tumor growth, characteristic of the CSC phenotype. interestingly, PD2 was found to be specifically overexpressed in a subpopulation of cells within mouse KC, KPC and human pancreatic tumors, which co-express CSC markers. The drug resistance property was impaired upon knockdown of PD2 with simultaneous alteration in the CSC phenotype and reduction in CD133 and MDR2 gene expression. Overall, my study identified that PD2 has a role in self-renewal and drug resistance of pancreatic CSCs. The second part of my dissertation was primarily focused at exploring the functional role of PD2 in pancreatic cancer cells. The ectopic overexpression of PD2 resulted in increased growth rate of tumor cells both in vitro and in vivo. Overexpression of PD2 led to increased growth, colony formation and migration. Interestingly, elevated expression of PD2 also increased the percentage of CSCs. Furthermore, in vivo studies revealed that PD2 overexpression leads to increased tumor volume and metastasis to distant secondary sites. These results were corroborated at the protein level where elevated expression of PD2 led to the up-regulation of c-Myc which is an important player in tumorigenesis and metastasis. In addition, the expression of PD2 in pancreatic cancer tissues and in vitro pancreatic progression model was elucidated. We demonstrated that the expression of PD2 was increased in the ducts present in the pancreatic cancer tissues when compared to the normal tissues. Likewise, the expression of PD2 was elevated in the transformed Human Pancreatic Nestin expressing (HPNE) cells when compared to the untransformed HPNE cells. Understanding the role of PD2 through cell lines led to my next aim to generate PD2 conditional knockout mice in order to substantiate our earlier work in cancer stem cells and acinar to ductal metaplasia during PC initiation. The animal model would be an important resource for understanding the role of PD2 in detail. Taken together, our findings demonstrate that PD2 is an essential member of the oncogene family that plays a significant role in facilitating drug resistance and cancer stem cell maintenance thereby acting as a positive regulator of cancer.

Summary : The second edition of Stem Cells: Scientific Facts and Fiction provides the non-stem cell expert with an understandable review of the history, current state of affairs, and facts and fiction of the promises of stem cells. Building on success of its award-winning preceding edition, the second edition features new chapters on embryonic and iPS cells and stem cells in veterinary science and medicine. It contains major revisions on cancer stem cells to include new culture models, additional interviews with leaders in progenitor cells, engineered eye tissue, and xeno organs from stem cells, as well as new information on "organs on chips" and adult progenitor cells. In the past decades our understanding of stem cell biology has increased tremendously. Many types of stem cells have been discovered in tissues that everyone presumed were unable to regenerate in adults, the heart and the brain in particular. There is vast interest in stem cells from biologists and clinicians who see the potential for regenerative medicine and future treatments for chronic diseases like Parkinson's, diabetes, and spinal cord lesions, based on the use of stem cells; and from entrepreneurs in biotechnology who expect new commercial applications ranging from drug discovery to transplantation therapies. Explains in straightforward, non-specialist language the basic biology of stem cells and their applications in modern medicine and future therapy Includes extensive coverage of adult and embryonic stem cells both historically and in contemporary practice Richly illustrated to assist in understanding how research is done and the current hurdles to clinical practice

Summary : Stem cells have a prominent role in normal life and also in pathogenesis of disorders. Today, these cells are clinically applicable in hematopoietic stem cell transplantation but expansion of their application in many more disorders needs more work. For safe and effective application of these cells, we need better knowledge of their biology, their interaction with other cells (especially supporting niche cells), growth, maturation and also immigration of stem cells through body in normal and abnormal conditions. Also for clinical application we need to understand better, their separation methods and safe manipulation. This book is written to clarify some aspects of stem cell biology, their characteristics, assessment of damage to cells during ex vivo manipulation and also their role in a model of cancers (chronic myeloid leukemia).

Summary : Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush’s watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.
