  • Publication number: 20240067924
    Abstract: 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.

  • Publication number: 20240046478
    Abstract: 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.

  • Publication number: 20230220335
    Abstract: The present invention relates generally to the field of cell biology of stem cells, more specifically the directed differentiation of pluripotent or multipotent stem cells, including human embryonic stem cells (hESC), somatic stem cells, and induced human pluripotent stem cells (hiPSC) using novel culture conditions. Specifically, methods are provided for obtaining neural tissue, floor plate cells, and placode including induction of neural plate development in hESCs for obtaining midbrain dopamine (DA) neurons, motor neurons, and sensory neurons. Further, neural plate tissue obtained using methods of the present inventions are contemplated for use in co-cultures with other tissues as inducers for shifting differentiation pathways, i.e. patterning.

  • Publication number: 20180369287
    Abstract: The present invention provides cell populations enriched for specific neural precursor markers and methods of using such cell populations for treatment of disorders associated with dysregulation of inhibitory neuronal function and/or imbalances in excitatory/inhibitory neuronal activity. In particular, the present invention provides cell populations for use as a cell-based therapeutic, and methods for purification and use of these neural precursor cells in transplantation to ameliorate neural disorders associated with aberrant neural function.
