This gelatin coating protocol for cell culture applications offers information regarding types of gelatin, surface coverage concentration, and tips for optimization. (sigmaaldrich.com)

Several (unsuccessful) attempts to build cell-like systems of minimal complexity fill the annals of science ( Hanczyc, 2009 ). (frontiersin.org)

In scaffold-based culture, cells are supported in all dimensions either by an artificial structure or by a polymer network known as a hydrogel. (sigmaaldrich.com)
which can be considered a sort of foundational paper for (or even the manifesto of) the modern approaches for constructing living artificial cells from scratch. (frontiersin.org)
Second, artificial organs function as laboratory models to study disease and effects of medicines much more accurately than simply growing cells in a dish. (lu.se)
She described cell sources and engraftment as major remaining barriers between patients and artificial lungs of the future. (lu.se)

Cell-free systems may be divided into two primary classifications: cell extract-based, which remove components from within a whole cell for external use, and purified enzyme-based, which use purified components of the molecules known to be involved in a given process. (wikipedia.org)
The cell extract-based type are susceptible to problems like quick degradation of components outside their host, as shown in a study by Kitaoka et al. (wikipedia.org)
The preparation of cell extract is simple, robust and inexpensive. (synthelis.com)
