  • Patent number: 12252683
    Abstract: Provided are automated cell culture systems and related in vitro cell culture methods, including for a co-culture of different cell populations having different cell culture conditions. For example, the system may comprise a bioreactor having a plurality of cell culture compartments, the bioreactor having a fluid port fluidly connected to the plurality of cell culture compartments. A pump fluidly connected to the fluid port can provide a cell culture medium to the plurality of culture compartments. A sensor is operably connected to at least one of the plurality of cell culture compartments for measuring at least one cell culture parameter. In this manner, a controller electronically connected the pump and sensor, is configured to automatically adjust a pump flow rate and/or a cell culture gas content to provide a desired steady-state cell culture parameter for facilitating cells interactions and collection of products representative of said interactions.

  • Publication number: 20240344022
    Abstract: Provided herein are stretch devices and related methods for controlled three-dimensional stretching of scaffolds supported on a stretchable substrate. A stretchable substrate is capable of receiving the three-dimensional scaffold, and a stretchable substrate holder is configured to connect to the stretchable substrate. An actuator is connected to the stretchable substrate holder to exert a cyclic stretch on the stretchable substrate and periodically stretch the three-dimensional scaffold connected to the stretchable substrate. A sample holder is configured to immerse the three-dimensional scaffold in a tissue culture media.

  • Publication number: 20240277322
    Abstract: Provided herein are self-collection devices for collecting and/or processing biofluids. The biofluid, such as saliva, is collected in a collection tube. A tube insert in the collection tube is configured to work with a cap having an integrated reservoir volume holding a reagent. Upon connecting the cap to the collection tube, the material in the reservoir volume is effectively introduced to or mixed with the sample in the collection tube. In this manner, there is no risk of user exposure to the reagent and no adverse impact on the ability to reliably mix reagent with sample. The device can then be shipped to a testing facility. Alternatively, a biomarker detection membrane may be used to detect more immediately, without shipping, presence or absence of a material in the sample. This provides for an almost instantaneous read-out that is incorporated into the self-collection device.

  • Publication number: 20140186841
    Abstract: A method, system, and apparatus for analysis of a biological sample includes receiving the sample, wherein the sample includes deoxyribonucleic acid (DNA), lysing the sample to obtain access to the DNA included in the sample, purifying the DNA in the sample to isolate the DNA from other components in the sample, amplifying the DNA, separating fragments of the amplified DNA, detecting the separated fragments using laser induced fluorescence, based on the detecting, generating a profile of the DNA in the received sample, comparing the generated profile with profiles of DNA stored in a database, and upon determining that the generated profile matches one of the stored profiles, identifying the source from which the stored profile was obtained, wherein the receiving, lysing, purifying, amplifying, and detecting are performed on corresponding portions of a microfluidic device, and wherein transporting the sample and the DNA to the portions of the microfluidic device and enabling the lysing, purifying, amplifying,
