Melhorou Rendimento / Pureza de hiPSC-CMs protocolos convencionais para diferenciação de células-tronco humanas no CMS são muitas vezes limitadas pela baixa produtividade e pureza; por exemplo, apenas 35-66% das hESC-CMs obtido via separação Percoll e formação do corpo cardíaca expressa lento miosina de cadeia pesada ou cTnT 6. A pureza das populações hiPSC-CM diferenciadas pode ser substancialmente aumentada, seleccionando para a expressão de um gene repórt...

As células estaminais pluripotentes humanas induzida (hiPSCs) estão entre os agentes mais promissores para a terapia celular regenerativo porque eles podem ser diferenciadas em uma gama potencialmente ilimitada e a quantidade de células que não são rejeitadas pelo sistema imunitário do paciente. No entanto, a sua capacidade de auto-replicação e diferenciação podem também levar à formação de tumor e, consequentemente, hiPSCs precisa ser totalmente diferenciadas em tipos de células específicos, tais como cardiomiócitos (CMS), células endoteliais (ECs), e células do músculo liso (SMCs ), antes da administração. Um dos métodos mais simples e mais comum de administração da célula é a injecção directa intramiocardial, mas o número de células transplantadas que são enxertados pelo tecido do miocárdio nativa é excepcionalmente baixa. Muito deste atrito pode ser atribuído ao ambiente citotóxica do tecido isquémico; No entanto, quando as células estaminais embrionárias de murídeo (CES) foram injectados directamente no miocárdio de corações não lesionados, óomente ~ 40% dos 5 milhões de células foram entregues retida durante 3-5 h 1, o que sugere que uma proporção substancial das células administradas saiu do local de administração, talvez por terem sido espremidos para fora através do percurso da agulha pelas altas pressões produzidas durante contração do miocárdio. Aqui, apresentamos métodos novos e substancialmente mais eficientes para a geração de cardiomiócitos hiPSC derivados (hiPSC-CMS) 2, células endoteliais (hiPSC-ECs) 3, e células musculares lisas (SMCs) 4. Notavelmente, este protocolo hiPSC-SMC é o primeiro a imitar a vasta gama de características morfológicas e funcionais observadas em somática SMCs 5 direccionando as células para um fenótipo de SMC contráctil ou predominantemente sintética. Também fornecemos um método de entrega de células que melhora a taxa de enxerto de células injectadas através da criação de uma citocina de fibrina contendo Patch sobre o local da injecção. O remendo parece melhorar a retenção de células, por meio de selagem da faixa da agulha para evitar que as células se sair do miocárdio, e a sobrevivência de células, através da libertação do factor de crescimento semelhante a insulina (IGF) ao longo de um período de pelo menos três dias.

pluripotent stem cell derived cardiac cells for myocardial repair

Humanos induzida células-tronco pluripotentes (hiPSCs) deve ser totalmente diferenciado em tipos específicos de células antes da administração, mas protocolos convencionais para diferenciar hiPSCs em cardiomiócitos (hiPSC-CMS), células endoteliais (hiPSC-ECs), e células musculares lisas (SMCs) são muitas vezes limitada pelo baixo rendimento, pureza e / ou pobre estabilidade fenotípica. Aqui, nós apresentamos novos protocolos para gerar hiPSC-CMs, -ECs, e -SMCs que são substancialmente mais eficiente do que os métodos convencionais, bem como um método para a combinação de injecção de células com um penso contendo citocina criado ao longo do local de administração. O remendo melhora tanto a retenção das células injectadas, por meio de selagem da faixa de agulha para impedir que as células de ser espremido para fora do miocárdio, e a sobrevivência de células, através da libertação do factor de crescimento semelhante a insulina (IGF), durante um período prolongado. Num modelo suíno de lesão de isquemia-reperfusão do miocárdio, a taxa de enxerto era mais do que duas vezes maior quando oAs células foram administrados com o remendo contendo citoquinas em comparação com as células, sem mancha, e o tratamento com ambos as células e o remendo, mas não apenas com as células, foi associada com melhorias significativas na função cardíaca e o tamanho do enfarte.

Caracterização de Diferenciada hiPSC-CMs, -ECs e -SMCs A capacidade diferencial de hiPSCs foram avaliados 2, 3, 4. Análises de citometria de fluxo de expressão de troponina T (TnT) sugerem que a pureza da população final hiPSC-CM pode exceder 90% (Figura 1A, 1B, painel B1). Quase todas as células ...

The overall goal of this video is to introduce a technique for differentiating human pluripotent stem cells into cardiomyocytes, and to demonstrate the use of these cells for studying myocardial repair after an ischemia reperfusion injury. This method can help answer key questions about engineering heart tissue with human iPS cell derived from cardiac cells for myocardial repair. The main advantage of this procedure is that it allows scientists to collect purified cardiomyocytes, smooth muscle cells, and endothelial cells, and generate heart tissue with these progenitor cells.Ling Gao is a post-doc in Doctor Zhang's own lab in UAB and Greg Walcott is a cardiologist in UAB hospital. Trina is a MRI specialist in UAB hospital. To induce pluripotent stem cells into cardiomyocytes, first, coat the wells of a six-well plate with growth-factor reduced gelatinous protein mixture cooled to 4 degrees Celsius.Then, refrigerate the plate overnight at 4 degrees Celsius. The next day, aspirate the gelatinous protein mixture and seed the plates with 100 million stem cells per well. Never keep the stem cells out of the incubator for more than 15 minutes.Also, always use fresh media. In this case, use mTeSR1 medium, supplemented with 10 micromolar of ROCK inhibitor. Then, culture the cells with 5%carbon dioxide at 37 degrees Celsius, and refresh the medium daily by gently aspirating away the old medium without touching the cells, and using a transfer pipette to apply fresh medium.Grow the cells until they are 90%confluent. Three days into the differentiation process, start checking for clusters of contracting cells. As soon as contractions are noted, which can take a week or so, collect the cells.Count the contracting cells using a hemocytometer, and then culture the cells on 10 centimeter plates at a concentration of one million cells per milliliter. It is also possible to make endothelial cells from stem cells, as well as smooth muscle cells. The processes are different, but are carefully detailed in the text protocol.First, surgically induce a myocardial infarction in a swine heart. Briefly perform a fourth intercostal thoracotomy to expose the left anterior descending coronary artery. Then, occlude the coronary artery using a ligature for 60 minutes.Defibrillate the heart as necessary. Suspend five milligrams of microspheres in one milliliter of fibrinogen solution, and load this into a syringe. Third, fill another syringe with one milliliter of thrombin solution.After an hour has passed, remove the ligature used to create the myocardial infarction. Then, position a plastic ring on the epicardium of the infarcted region, and simultaneously inject the microspheres and fibrinogen and the thrombin solutions into the ring. Allow the mixture of solutions to solidify, which takes about 30 seconds.This makes the patch. Then, insert the needle of the cell-containing syringe through the patch into the infarcted myocardium and inject the cells. Now, close the muscle layers, subcutaneous tissue, and the chest wall with 30 or 20 Monocryl suture, depending on the animal's size.One week and four weeks after the procedure, evaluate the animal's cardiac function using a cardiac MRI. As described by the first presented protocol, human pluripotent stem cells were differentiated into cardiomyocytes. To assess their purity, flow cytometry for cardiac troponin T showed it was present in excess of 90%of cells.Other markers were also observed. Nearly all of the cells expressed slow myocin heavy chain, and nearly all the cells expressed alpha sarcomeric actin. About one quarter of the cells expressed 2v isoform of myosin light chain, a marker for ventricular cardiomyocytes.In comparing stem cell lines, it was found that the efficiency of the differentiation was substantially higher with cells from the GRiPS line than from the PCBC16iPS line. Using the patch-mediated cell transplantation protocol, a mixture of cells, made up of differentiated cardiomyocytes, endothelial cells, and smooth muscle cells was injected into the injured tissue. Four weeks later, more cells were retained with the patch than without it.Within one week, treatment using the cell injection with the patch resulted in the most improvement of the infarct size. Also, there was no appreciable difference in injecting with just cardiomyocytes compared to injecting with three cell types. After watching this video, you should have a good understanding on how to differentiate human iPS cells into three different cardiac ligature cells, including cardiomyocytes, smooth muscle cells, and endothelial cells.You should also have a good understanding of how to generate human heart tissue with the progenitor cells for myocardial repair. Since the development, this technique has advanced investigations on myocardial repair and stem cell tissue engineering. It should be noted that when attempting this procedure, it is very important to use high quantity of iPS cells and their cardiac derivatives.
