METHODS OF PREPARING PERSONALIZED BLOOD VESSELS
The present disclosure relates to methods of preparing personalized blood vessels, useful for transplantation with improved host compatibility and reduced susceptibility to thrombosis. Also provided are personalized blood vessels produced by the methods and use thereof in surgery.
EXTERNAL CIRCULATION RENEWAL DEVICE OF CULTURE MEDIA AND VENTILATION DEVICE FOR BIOREACTOR
The present disclosure provides a bioreactor, which includes a tank configured to contain a mixture of animal cells and a liquid; and a first ventilation device arranged outside the tank and including a first gas distributor, the first gas distributor being configured to transmit a gas to the liquid separated from the animal cells. The bioreactor further includes a dialysis component, which is arranged outside the tank and comprises a dialysis filter. The bioreactor further includes a second ventilation device arranged in the tank and configured to transmit the gas to the mixture in the tank.
CELL PROLIFERATION BIOREACTOR
A bioreactor includes a culture medium vessel housing culture medium. The culture medium vessel further includes a first side surface including a first transparent optical window; and a second side surface parallel to the first surface and including one or more sensor adapters to fix optical sensors. A cell retention vessel is disposed underneath and connected to the culture medium vessel, the cell retention vessel housing biological cells and having: a top surface that intersects a base of the culture medium vessel, and a second transparent optical window indented into the top surface at a first corner of the top surface. A semipermeable membrane is disposed at a bottom of the cell retention vessel, and a frame comprising a grid is disposed underneath the semipermeable membrane.
Process for Purifying Target Substances
A process for purifying a composition comprising water, a target substance, impurities and optionally cells, the process comprising the steps (A) and (B): (A) preparing a liquid feedstock by performing step (Ai) and/or (Aii) on the composition: (Ai) removing at least some of the cells from the composition; (Aii) concentrating the composition by removing water therefrom; and (B) passing the liquid feedstock through an apparatus comprising at least two processing units, each such unit producing a product stream containing purified target substance and optionally a waste stream comprising at least some of the impurities, wherein each unit comprises specified components (i) to (v). The units may be essentially the same except for a device they contain, leading to advantages in terms of simplicity, cost and ease of operation, lower risk of operator error, easier maintenance and lower inventory of spare parts.

Monitoring state deviations in bioreactors
The invention relates to a system (100) for monitoring deviations of a state of a cell culture in a bioreactor (104, 106) from a reference state of a cell culture in a reference bioreactor (102). The bioreactor comprises the same medium (M1) as the reference bioreactor. The system comprises: •—a storage medium (114) comprising: •a PACO-reference profile (116) indicative of a deviation of a CO2 off gas rate (ACO.sub.R-M-.sub.ti) measured in the reference bioreactor from a predicted CO2 off gas rate (ACO.sub.R-EXP-ti) of the reference bioreactor; •a data object comprising a medium-specific relation (136) between the pH value of the medium (M1) and a respective fraction of CO2 gas in a gas volume when said medium is in pH-CO2 equilibrium state with said gas volume and lacks the cell culture; •—an interface (128) for receiving (212) a current CO2 off gas rate (ACO.sub.Bi-M-ti, ACO.sub.B2-M-.sub.t i) and a current pH value (pH.sub.Bi-ti) of the medium of the bioreactor (104, 106); •—a comparison unit (130) configured for computing (214, 216): •a PACO value (PACO.sub.B1-tir PACO.sub.Bi-ti) the PACO-value being indicative of a deviation of a CO2 off gas rate (ACO.sub.Bi-M-ti, ACO.sub.B2-M-.sub.ti) measured in the bioreactor from a predicted CO2 off gas rate (ACO.sub.B1-EXP-ti, ACO.sub.B2-E xp-.sub.t i). a difference between the computed PACO value (PACO.sub.Bi-ti, PACO.sub.B2-ti) and a respective reference PACO value (PACO.sub.R-ti) in the PACO-reference profile (116).
