| 1 | Role of Hox genes in stem cell differentiation显示文摘Hox genes are an evolutionary highly conserved gene family. They determine the anterior-posterior body axis in bilateral organisms and influence the developmental fate of cells. Embryonic stem cells are usually devoidof any Hox gene expression, but these transcription factors are activated in varying spatial and temporal patterns defining the development of various body regions. In the adult body, Hox genes are among others responsible for driving the differentiation of tissue stem cells towards their respective lineages in order to repair and maintain the correct function of tissues and organs. Due to their involvement in the embryonic and adult body, they have been suggested to be useable for improving stem cell differentiations in vitro and in vivo. In many studies Hox genes have been found as driving factors in stem cell differentiation towards adipogenesis, in lineages involved in bone and joint formation, mainly chondrogenesis and osteogenesis, in cardiovascular lineages including endothelial and smooth muscle cell differentiations, and in neurogenesis. As life expectancy is rising, the demand for tissue reconstruction continues to increase. Stem cells have become an increasingly popular choice for creating therapies in regenerative medicine due to their self-renewal and differentiation potential. Especially mesenchymal stem cells are used more and more frequently due to their easy handling and accessibility, combined with a low tumorgenicity and little ethical concerns. This review therefore intends to summarize to date known correlations between natural Hox gene expression patterns in body tissues and during the differentiation of various stem cells towards their respective lineages with a major focus on mesenchymal stem cell differentiations. This overview shall help to understand the complex interactions of Hox genes and differentiation processes all over the body as well as in vitro for further improvement of stem cell treatments in future regenerative medicine approaches. | Anne Seifert David F Werheid Silvana M Knapp Edda Tobiasch | 2015 | World Journal of Stem Cells2015，7，3： | 10 |
| 2 | Hepatoid adenocarcinoma of the colon in a patient with inflammatory bowel disease显示文摘A case is presented of a 36-year-old male with primary sclerosing cholangitis-associated inflammatory bowel disease(PSC-IBD) and two synchronous stage 1 adenocarcinomata of the colon,who was initially treated with a subtotal colectomy with ileostomy.One year later,the patient presented with extensive intra-abdominal lymphadenopathy and peritoneal carcinomatosis,as well as a markedly elevated serum level of alpha-fetoprotein(AFP).Fine needle aspiration biopsy of a porta hepatis lymph node revealed a metastatic hepatoid adenocarcinoma.Subsequent review of the previous colectomy specimen showed that one of the previously identified adenocarcinomata had features suggestive of a hepatoid colonic adenocarcinoma.The patient was subsequently treated with a cytotoxic regimen of FOLFOX(oxaliplatin,leucovorin,5-fluorouracil) and bevacizumab,with stable results being achieved after six months.This case presents the first known report of PSC-IBD associated with synchronous typical and hepatoid adenocarcinomata of the colon and highlights the importance of considering hepatoid adenocarcinoma as a differential diagnosis in patients with an increasing serum AFP level. | Yuanyuan Chen David F Schaeffer Eric M Yoshida | 2014 | World Journal of Gastroenterology2014，20，35： | 6 |
| 3 | Mechanisms of fibrinolysis resistance and potential targets for thrombolysis in acute ischaemic stroke: lessons from retrieved stroke emboli显示文摘There has been growing interest and insight into the histological composition of retrieved stroke emboli.One of the main focuses of the stroke clot analysis literature has been the implications of clot composition on mechanical thrombectomy procedures.However,the holy grail of clot analysis may not be in the field of clot-device interaction,but rather,in understanding mechanisms of fibrinolysis resistance.The mechanisms underlying the low response to fibrinolytic therapy,even with the newer,more powerful agents,remain poorly understood.While factors such as embolus size,location and collateral status influence alteplase delivery and recanalisation rates;compositional analyses focused on histological and ultrastructural characteristics offer unique insights into mechanisms of alteplase resistance.In this review,we strive to provide comprehensive review of current knowledge on clot composition and ultrastructural analyses that help explain resistance to fibrinolysis. | Waleed Brinjikji Oana Madalina Mereuta Daying Dai David F Kallmes Luis Savastano Yang Liu Shahid M Nimjee Raul G Nogueira Mehdi Abbasi Ramanathan Kadirvel | 2021 | Stroke & Vascular Neurology2021，6，4： | 2 |
