It is important to use beating, functional spheroids for 3D bioprinting. If spheroids are not beating, continuing to use them will invariably result in a non-functional 3D bioprinted patch.
One benefit of this approach is the ability to manipulate the cell content of the patch by varying the total number of cells and the percentage of cardiomyocytes, endothelial cells, and fibroblasts in the spheroids. This allows for many different types of cardiac patches to be printed, with varying histolog...

3D biyoprintleme için birçok farklı yöntem vardır 1 , 2 , 3 . 3D biyoprinting, mürekkep püskürtmeli biyoprint, mikro ekstrüzyon biyoprint, lazer yardımlı biyoprint, metotların bir kombinasyonu veya daha yeni yaklaşımlar gibi örneklerle baskı teknolojisi 1 ile sık sık sınıflandırılır. 3D biyoprinting, iskeleye bağlı olmayan veya iskeleye bağlı yöntemler olarak sınıflandırılabilir. 3D biyoprintinin çoğu metodu, biyo-materyallere, örn., Biyometrik bağlantılar 5 veya iskele 6&#39;ya ihtiyaç duyulduğunda, iskeleye bağlıdır. Bununla birlikte, iskele bağımlı 3D biyoprinting, iskele materyalinin immünojenisitesi, patentli bioink maliyeti, bozunma ürünlerinin yavaş hızı ve toksisitesi gibi birçok konuyu ve sınırlamaları 4 , 7 ile karşı karşıya bırakıyor. ScafKüresel olmayan kardiyak doku mühendisliği, iskeleye bağlı doku mühendisliğinin bu dezavantajlarının üstesinden gelebilecek potansiyele sahip 8 olarak denenmiştir. Bununla birlikte, yazarların bu makalede belirttiği gibi, biofabrikasyon sürecinde sferoidleri sabit yerlerde sağlam bir şekilde tutmak ve konumlandırmak zordu. 3D biyoprint ve sferoya dayalı doku mühendisliğinin birlikte kullanımı bu zorlukların üstesinden gelme potansiyeline sahiptir. Bu protokolde, yalnızca sfero formundaki hücreleri kullanarak, diğer biyomalzemeler olmadan kardiyak dokunun 3D biyoprintini açıklıyoruz. İskeletsiz sferoid tabanlı 3B biyoeneratörler 9 , vakumlu emici kullanarak tekli sferoidleri alıp iğne dizisine yerleştirme özelliğine sahiptir. 3D biyoprintide bir iğne dizisine küre biçimlendirme konsepti , eski Japonya&#39;da iğne dizilerinin (&quot; kenzan &quot; olarak bilinir) kullanılmasından esinlenmiştirÇiçek düzenleme düzenlemeleri, ikebana. Bu sistem, sferoidlerin herhangi bir konfigürasyonda tam olarak konumlandırılmasını sağlar ve bireysel sferoitler, bir 3D biyoprote edilmiş doku oluşturmak için kısa bir süre boyunca kaynaşarak sonuçlanır. Bu yöntem, bu sayede, sferoidlerin kolaylıkla manipüle edilmesine ve iskelesiz organ biyofabrasyonunun geleceği için potansiyel etkilere sahip olmasına izin verir.

creation of cardiac tissue exhibiting mechanical integration of spheroids using 3d bioprinting

Bu protokol, sadece hücreler kullanılarak, biyomalzemeler kullanılmadan kalp dokusunun 3D biyoprintini açıklamaktadır. Kardiyomiyositler, endotel hücreleri ve fibroblastlar önce izole edilir, sayılır ve istenen hücre oranlarında karıştırılır. Bunlar, ultra-düşük ek 96 delikli plakalar içinde bireysel kuyularda birlikte kültürlenir. 3 gün içinde sopoidler atılır. Bu sfero daha sonra vakum emiş kullanarak bir meme tarafından toplanır ve bir 3D bioprinter kullanarak bir iğne dizisi üzerine monte edilir. Daha sonra sferoidlerin iğne dizisi üzerinde sigortalanmasına izin verilir. 3D biyoprintten üç gün sonra, sferoidler, bozulmamış bir yama olarak çıkarılır; bu zaten kendiliğinden dayaktır. 3D biyoprote edilmiş kalp yamaları bileşen küremsiklerin mekanik entegrasyonunu sergiler ve kalp dokusunun yenilenmesinde ve kalp hastalığının 3D modellerinde son derece umut vericidir.

Adım 4.4&#39;ün (ortak kültür) sonunda, yerçekimi ile küre biçimlendirmek için her kuyucuktaki hücreler ultra-düşük ek 96-kuyucuk U-alt plakalarının tabanında birikmelidir. Bu sferoitler, hiPSC-CM, HCF&#39;ler ve HUVEC&#39;leri içerir ve iki boyutlu projeksiyon ile dairesel görünmeleri gereken ışık mikroskopisi altında görsel olarak incelenebilir ( Şekil 1 ). 6.3.
