Publication number: 20240067924Abstract: Cranial placodes are embryonic structures essential for sensory and endocrine organ development. The efficient derivation of cranial placodes from human pluripotent stem cells is disclosed where the timed removal of the BMP inhibitor Noggin, a component of the dual-SMAD inhibition strategy of neural induction, triggers placode induction at the expense of CNS fates. Further fate specification at the pre-placode stage enables the selective generation of placode-derived trigeminal ganglia capable of in vivo engraftment, mature lens fibers and anterior pituitary hormone-producing cells that upon transplantation produce hormones including, but not limited to, human growth hormone and adrenocortiocotropic hormone in vivo. Alternatively, anterior pituitary hormone-producing cells are generated in cell culture systems in vitro.Type: ApplicationFiled: December 21, 2022Publication date: February 29, 2024Applicant: MEMORIAL SLOAN-KETTERING CANCER CENTERInventors: Stuart Chambers, Lorenz Studer, Zehra Dincer, Bastian Zimmer

Publication number: 20240046478Abstract: Described herein are techniques to regulate the treatment of a culture of cells having cells corresponding to different cell categories. Some techniques may be used together with a cell imaging and incubation system including an imaging sensor configured to obtain an image of the culture and an incubator configured to incubate the culture. Regulation of treatment of the culture may be based on the processing of an image of the culture obtained by the imaging sensor of the system. The processing may include segmenting the image of the culture into multiple image segments by assigning individual pixels of the image to corresponding cell categories. According to some embodiments, the techniques include determining, based on the image segments, an amount of the culture corresponding to a particular cell category. The amount of the culture corresponding to the particular cell category may inform regulation of the treatment of the culture.Type: ApplicationFiled: July 25, 2023Publication date: February 8, 2024Applicant: Amgen Inc.Inventors: Stuart Chambers, Britney L. Ragunton, Devin Wakefield
