This invention relates to methods and devices that improve cell culture efficiency. They include the use of gas permeable culture compartments that reduce the use of space while maintaining uniform culture conditions, and are more suitable for automated liquid handling. They include the integration of gas permeable materials into the traditional multiple shelf format to resolve the problem of non-uniform culture conditions. They include culture devices that use surfaces comprised of gas permeable, plasma charged silicone and can integrate traditional attachment surfaces, such as those comprised of traditional tissue culture treated polystyrene. They include culture devices that integrate gas permeable, liquid permeable membranes. A variety of benefits accrue, including more optimal culture conditions during scale up and more efficient use of inventory space, incubator space, and disposal space. Furthermore, labor and contamination risk are reduced.

A method for fabricating an in vitro vessel includes forming a substrate that defines a microfluidic passage therein extending along a longitudinal axis and defined by an inner surface, positioning the substrate in a vertical orientation whereby an acute angle is formed between the longitudinal axis of the microfluidic passage and the direction of gravity, and culturing a plurality of first cells in the microfluidic passage while the substrate is disposed in the vertical orientation whereby an annular layer of the plurality of first cells is formed in the microfluidic channel, wherein the layer of the plurality of first cells defines a lumen extending longitudinally through the microfluidic channel.

Methods to produce helper dependent adenovirus, and a cell, vector and kit useful in that regard, are provided.

Composites based on a polymer and a mixture of proteins derived from a MaSp (major ampullate spidroin) protein are provides. Further, methods for preparation of same, and method of use of the composites are provided.

Methods of culturing and manufacturing of cells on a large-scale level are disclosed. Particularly, a manufacturing system and device, and methods of using the system and device for culturing and manufacturing cells in hollow fibers made from alginate polymers are provided.

A reinforced biocompatible scaffold facilitates integration of biological tissue. The reinforced scaffold comprises a porous biocompatible scaffold and an arrangement of at least one biocompatible filament embedded within and fixed to the biocompatible scaffold, and/or at least one biocompatible conduit embedded within and fixed to the biocompatible scaffold.

A method and apparatus of aseptic processing and production of cells in a non-sterile enclosure apparatus without chemical biocides is disclosed, by controlling the level of humidity throughout the enclosure to 25% relative humidity (RH) or less, and preferably 20% or 15% or less RH. In addition, the temperature is controlled to 37° C., and consistent gas flow is maintained the enclosure. Colony forming units from microbial contamination detected by environmental monitoring within the enclosure are significantly reduced in this method.

The invention relates to improved culture methods for expanding epithelial stem cells and obtaining organoids, to culture media involved in said methods, and to uses of said organoids.

Disclosed herein are pluripotent stem cells cultured with one or more peptide and methods of isolating said stem cells.
