  • Publication number: 20250250531
    Abstract: The invention primarily relates to a method for isolating and characterizing nucleus pulposus progenitor cells. The method initially involves cutting nucleus pulposus tissue into multiple tissue blocks and then enzymatically digesting these blocks. After digestion, these tissue blocks are cultured in a culture dish. When cells form clusters at the bottom of the dish, specific embryonic stem cell genes (such as Nanog, Oct-4, SOX2) are used to select nucleus pulposus progenitor cells from the clusters. Furthermore, this method employs specific proteins and genetic markers to select nucleus pulposus progenitor cells with mobility and/or mesenchymal stem cell characteristics, as well as to further select cells with anti-inflammatory abilities. Finally, the invention discloses a use of the nucleus pulposus progenitor cells obtained by the method in the manufacture of a pharmaceutical composition for the treatment of lower back pain, offering a new strategy for the treatment of lower back pain.

  • Patent number: 12072832
    Abstract: Apparatus and methods for high-speed drivers are provided herein. In certain embodiments, a high-speed driver multiplexes two or more data streams. The high-speed driver is implemented with a mux-then-driver topology that provides multiplexing in a predriver circuit. Thus, the multiplexer is eliminated from the full rate output path to relax timing. Driver amplitude control schemes are also disclosed in which a controllable driver includes a group of differential series source transistor (SST) driver slices that are connected in parallel with one another to drive a pair of output terminals, and a group of attenuator slices that are connected in parallel with one another across the pair of output terminals. Additionally, the controllable driver includes a control circuit that activates an attenuator slice for each SST driver slice that is decommissioned to provide output amplitude control.
