3D Cell Culture: An Introduction

Overview DOI: Cell culture in two dimensions has been routinely and diligently undertaken in thousands of laboratories worldwide for the past four decades. However, the culture of cells in two dimensions is arguably primitive and does not reproduce the anatomy or. However, the culture of cells in two dimensions is arguably primitive and does not reproduce the anatomy or physiology of a tissue for informative or useful study. Creating a third dimension for cell culture is clearly more relevant, but requires a multidisciplinary approach and multidisciplinary expertise. When entering the third dimension, investigators need to consider the design of scaffolds for supporting the organisation of cells or the use of bioreactors for controlling nutrient and waste product exchange.

Two-Dimensional (2D) and Three-Dimensional (3D) Cell Culturing in Drug Discovery

A 3D cell culture is an artificially created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions. Unlike 2D environments e. Approximately spheroids are usually cultured per bioreactor. This work focused on the importance of the extracellular matrix and the ability of cultures in artificial 3D matrices to produce physiologically relevant multicellular structures, such as acinar structures in healthy and cancerous breast tissue models. These techniques have been applied to for in vitro disease models used to evaluate cellular responses to pharmaceutical compounds. Eric Simon, in a NIH SBIR grant report, showed that Electrospinning could be used to produced nano- and submicron-scale polystyrene and polycarbonate fibrous mats now known as scaffolds specifically intended for use as in vitro cell substrates.

3D Cell Culture

Cell culture techniques are ubiquitous in areas of developmental biology, drug discovery, regenerative medicine and protein production. Since the introduction of cell culture techniques, cells have been cultured in two-dimensions, attached to tissue culture plasticware or ECM attachment proteins. Cells in the physiological environment have constant interaction with the extracellular matrix , regulating complex biological functions like cellular migration, apoptosis, transcriptional regulation, and receptor expression 1. In-vitro experimental data cannot be translated into clinical trials completely 2 when cells are grown in 2D conditions since complicated cellular signals between cells and its matrix cannot be reproduced 3.

Overview DOI: By mimicking crucial features of in vivo environment, including cell—cell and cell—extracellular matrix interactions, 3D cell culture enables proper structural. By mimicking crucial features of in vivo environment, including cell—cell and cell—extracellular matrix interactions, 3D cell culture enables proper structural architecture and differentiated function of normal tissues or tumors in vitro. Thereby 3D cell culture realistically models in vivo tissue conditions and processes, and provides in vivo like responses. Since its early days in the s, 3D cell culture has revealed important insights into mechanisms of tissue homeostasis and cancer, and accelerated translational research in cancer biology and tissue engineering.

Cell culture is an indispensable in vitro tool used to improve our perception and understanding of cell biology, the development of tissue engineering, tissue morphology, mechanisms of diseases and drug action. Efficient cell culturing techniques both in vitro and in vivo allow researchers to design and develop new drugs in preclinical studies. Two-dimensional 2D cell cultures have been used since s and are still a dominant method in many biological studies.

Methods and Protocols

Беккер постоял минуту, уперев руки в бока. Затем поднял коробку, поставил ее на стол и вытряхнул содержимое. Аккуратно, предмет за предметом, перетряхнул одежду. Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант. - Да, - сказал Беккер.

И вдруг Сьюзан увидела, что кнопка вызова вовсе не мертва, а просто покрыта слоем черной сажи. Она вдруг начала светиться под кончиком пальца. Электричество. Окрыленная надеждой, Сьюзан нажала на кнопку. И опять за дверью что-то как будто включилось. Она услышала, что в кабине работает вентиляция. Лифт .

3D Cell Culture: An Introduction

 - Мою колонку перепечатывают в Соединенных Штатах, у меня отличный английский. - Мне говорили, - улыбнулся Беккер.

 Вирус? - холодно переспросил директор.  - Вы оба думаете, что в нашем компьютере вирус. Бринкерхофф растерянно заморгал. - Да, сэр, - сказала Мидж.

Мидж всегда думала, что директорский кабинет следовало оборудовать здесь, а не в передней части здания, где он находился. Там открывался вид на стоянку автомобилей агентства, а из окна комнаты для заседаний был виден внушительный ряд корпусов АНБ - в том числе и купол шифровалки, это вместилище высочайших технологий, возведенное отдельно от основного здания и окруженное тремя акрами красивого парка. Шифровалку намеренно разместили за естественной ширмой из высоченных кленов, и ее не было видно из большинства окон комплекса АНБ, а вот отсюда открывался потрясающий вид - как будто специально для директора, чтобы он мог свободно обозревать свои владения.
