Özet: Embriyonik kök hücre, embriyoda erken evrede bulunan totipotent kök hücreler olarak tanımlanırlar. Embriyonik kök hücreler, erken embriyonik dönemde inner cell mass (ICM) kısmından elde edilir ve in vitro olarak bütün somatik hücrelere dönüşebilme yeteneği vardır.

Kök hücreler en basit anlatımıyla vücudumuzu oluşturan hücrelerin kaynaklarıdır. Yaşlanırken bozulan, hastalanan ve ölen dokularımızı yenilerler. Kök hücreler kendilerini yenileyebilme ve organizmanın birçok farklı hücresine de dönüşebilme özelliğine sahiptirler.

Kök hücreler vücudumuzda pek çok doku ve organda bulunur. Kemik iliği, Sinir sistemi, Beyin, Sindirim sistemi, Kalp, Akciğer, Cilt, Yağ dokusu ve özellikle Bebek Kordon Kanı ve Göbek Kordonu kök hücre odakları barındırırlar.

Embriyonik kök hücreler memeli blastosistindeki iç hücre kitlesinden elde edilen özel pluripotent hücrelerdir. Kendini yenileme ve her üç germ tabakasının da hücrelerine farklılaşabilme yetenekleri rejeneratif tıpta kullanılabilmeleri umudunu doğurmuştur.

لعلاج باستخدام الخلايا الجذعية هو زراعة خلايا بشرية أو حيوانية لتعويض الخلايا أو الأنسجة التالفة في محاولة لعلاج الأمراض. قد يستخدم العلاج الخلوي والعلاج الجيني معا للوصول لأفضل النتائج. أي استخدام الخلايا الجذعية للعلاج أو الوقاية من مرض أو حالة معينة.

عبر حسابها في تويتر، حذرت سفارة السعودية في الصين مواطنيها من إدعاءات علاج بعض الأمراض المستعصية هناك. وفي بيان، أشارت السفارة إلى أن العلاج بالخلايا الجذعية ما زال في طور التجارب، ولا يوجد أي مركز معتمد للعلاج بالخلايا الجذعية في الصين حاليا. وأفادت السفارة بأن الملحقية الصحية في بكين لديها اقرأ المزيد

Stem cell therapy has been a successful treatment for many conditions involving the immune system. Embryonic stem cells have recently been used successfully to treat Lyme’s disease symptoms. A case study reported that their patient reported reduced fatigue, insomnia, and is able to concentrate better during the day.

Borreliosis diagnostics is often based on the clinical appearance together with anamnesis and the evidence of specific antibodies. Fundamentally, a positive Borrelia antibody test is separately no indicator for a therapy or reflects the clinical manifestations. In this case, detection of Borrelia-specific effector T-cells can provide further diagnostic assistance. The AID LymeSpot Kit اقرأ المزيد

People who might benefit from stem cell therapies include those with spinal cord injuries, type 1 diabetes, مرض باركنسون, amyotrophic lateral sclerosis, Alzheimer’s disease, heart disease, stroke, حروق, cancer and osteoarthritis.

Diseases Treated with Stem Cells. Brain Cancer. Retinoblastoma. Ovarian Cancer. Skin Cancer: Merkel Cell Carcinoma. Testicular Cancer. Tumors abdominal organs Lymphoma. Non-Hodgkin’s lymphoma. Hodgkin’s Lymphoma.

Targeting drugs to cancer tissues is a major challenge in cancer treatment. الخلايا الجذعية الوسيطة (اللجان الدائمة) are known for their ability to find and target tumor cells in the body, but using MSCs for drug delivery has been tricky, because upon loading with drugs, MSCs lose their viability and migratory اقرأ المزيد

Victoza (liraglutide) was approved June 17, 2019, for pediatric patients 10 years of age and older for the treatment of type 2 diabetes. This is the first non-insulin drug approved to treat type 2 diabetes in children since metformin was approved for pediatric patients in 2000.

A new pill to lower blood sugar for people with type 2 diabetes was approved by the U.S. Food and Drug Administration on Friday. The drug, Rybelsus (semaglutide) is the first pill in a class of drugs called glucagon-like peptide (GLP-1) approved for use in the United States.

There are currently two approved drugs to treat ALS: riluzole, which can extend lifespan by an average of a few months and has been on the market for 25 years, and the 2017-approved edaravone, which was shown in clinical trials to help patients function for longer into their disease

Ofatumumab is first self-administered, targeted B-cell treatment for relapsing MS. The first self-administered, targeted B-cell treatment for relapsing multiple sclerosis (آنسة) received FDA approval

Stem cells promote life extension by replacing the damaged and old cells, and have, therefore, emerged as a powerful tool in the fight against aging. لكن, as the years go by, the quantity and function decline, until eventually, the old or damaged cells cannot be replaced, leading to aging.

A couple of early stem cell studies have shown limited success in cartilage or bone regrowth, which is the only outcome that could potentially cure arthritis. Stem cells seem to be ideal for replacement of damaged joint tissue.

The promising potential of stem cell therapy has given rise to initially encouraging clinical results. While doctors in North America and Western Europe continue to study stem cell therapy, rigorously evaluating its potential benefits, necessity triggered application of this science in clinical practice in Ukraine almost 20 twenty years ago. اقرأ المزيد

Intravenous injection of bone marrow derived stem cells (اللجان الدائمة) in patients with spinal cord injuries led to significant improvement in motor functions, researchers . For more than half of the patients, substantial improvements in key functions — such as ability to walk, or to use their hands — were observed اقرأ المزيد

Stem–cell therapy is the use of stem cells to treat or prevent a disease or condition. As of 2016, the only established therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone-marrow transplantation, but the cells can also be derived from umbilical cord blood.

Diseases Treated with Stem Cell Transplants Acute leukemia. Amegakaryocytosis or congenital thrombocytopenia. Aplastic anemia or refractory anemia. Chronic lymphocytic leukemia. Familial erythrophagocytic lymphohistiocytosis. Myelodysplastic syndrome of another myelodysplastic disorder. Osteopetrosis.

Stem cell therapy can cost anywhere between $8000 – $30,000 USD per treatment for expanded mesenchymal stem cells.

ИсторияОписания шизофреноподобных симптомов встречаются уже в XVII веке до нашей эры, в «Книге Сердец», — части древнего египетского папируса Эберса[35]. Изучение древних греческих и римских источников говорит о том, что, вероятно, в обществах того времени были осведомлены о психотических расстройствах, но не встречается описаний, которые удовлетворили бы сегодняшним критериям шизофрении[36]. اقرأ المزيد
