INTEGRATED CIRCUIT WITH BIOFETS AND FABRICATION THEREOF

An IC includes a source region and a drain region in a semiconductor layer. A channel region is between the source region and the drain region. A sensing well is on a back surface of the semiconductor layer and over the channel region. An interconnect structure is on a front surface of the semiconductor layer opposite the back surface of the semiconductor layer. A biosensing film lines the sensing well and contacts a bottom surface of the sensing well that is defined by the semiconductor layer. A coating of selective binding agent is over the biosensing film and configured to bind with a cardiac cell.

ORGANOTYPIC DRG-PERIPHERAL NERVE CULTURE SYSTEM
20220003742 · 2022-01-06 · ·

Techniques and systems are disclosed for a bioassay that is an in vitro mimic of peripheral nerve generation using the sensory neurons that innervate the peripheral nervous system. In some embodiments, the techniques may assist in detecting the bioactivity or potency of nerve grafts (e.g., processed, acellular human allografts) for fostering or supporting peripheral nerve regeneration. In various embodiments, techniques comprise affixing a harvested sensory neuron (e.g., a DRG) to a nerve graft segment to form a test construct; culturing the test construct in a medium; analyzing the test construct to indicate the amount of outgrowing peripheral nerve structure; and determining the potency of the nerve graft from a metric derived from the analysis. In some embodiments, techniques and materials may be used to test the effect of a varied test condition on peripheral nerve growth.

Methods and kits for predicting the risk of having or developping hepatocellular carcinoma in patients suffering from cirrhosis

Plasma levels of different sub-populations of microvesicles (endothelial, leukocyte, platelet and hepatocyte) were measured by flow cytometry or ELISA/filtration on blood samples from 125 patients with cirrhosis, for which 36 of them were diagnosed with HCC at inclusion. The inventors show that the levels of microvesicles of endothelial origin (CD62E+) could predict the occurrence of HCC in patients with cirrhosis. Therefore the present invention relates to a method for determining whether a patient suffering from cirrhosis is at risk of having or developing hepatocellular carcinoma comprising determining the level of endothelial-derived microvesicles (e.g. by flow cytometry) in a blood sample obtained from the patient.

MONITORING HOST CELL CONTAMINATION OF VIRUS-BASED BIOLOGICAL PRODUCTS
20210332419 · 2021-10-28 · ·

The invention relates to the production of biopharmaceuticals and, more particularly, to a novel method of monitoring for contamination of such products with components of any host cells used or involved in the manufacturing process. The method comprises a step of determining the presence in a biopharmaceutical (e.g. a therapeutic phage composition) of a ribosomal subunit protein unique to bacteria (or protein fragments thereof) or a nucleic acid molecule comprising a nucleotide sequence derived from a gene encoding a ribosomal subunit protein unique to bacteria.

NOVEL RENAL PROGENITOR CELL MARKER AND METHOD FOR CONCENTRATING RENAL PROGENITOR CELLS USING SAME
20210332329 · 2021-10-28 ·

A method for concentrating renal progenitor cells involves extracting MET-positive cells and/or AGTR2-positive cells from a renal progenitor cell-containing cell population. The MET-positive cells and/or AGTR2-positive cells are extracted using an anti-MET antibody and/or an anti-AGTR2 antibody. The renal progenitor cell-containing cell population is obtained from pluripotent stem cells. The renal progenitor cells are OSR1 (odd-skipped related 1)-positive and SIX2 (SIX Homeobox 2)-positive.

CELL ATLAS OF THE HEALTHY AND ULCERATIVE COLITIS HUMAN COLON

The present invention provides for a human cell atlas of the colon from healthy and diseased subjects. The atlas was obtained by single sequencing of about 117,000 cells. The present invention discloses novel markers for cell types. Moreover, genes associated with disease are identified in the colon and colon specific cell types. The invention provides for diagnostic assays based on gene markers and cell composition, as well as target cell types that express genes associated with disease. Finally, disclosed are novel cell types and methods of quantitating, detecting and isolating the cell types.
