A digital biosensor for assaying a target nucleic acid and methods of using the biosensor for digitally detecting the target nucleic acid are disclosed wherein the biosensor includes a substrate having a substrate surface and at least two electrodes, a linker molecule having a first moiety conjugated to the substrate surface, a ribonucleoprotein (RNP) conjugated to a second moiety of the linker molecule, and a guide ribonucleic acid (gRNA) having a first sequence capable of binding to the inactive RNP and a second sequence capable of binding to the target nucleic acid.

Immobilized RNPs for sequence-specific nucleic acid capture and digital detection

Method for reprogramming differentiated cells into lineage restricted progenitor cells is provided. The method may include contacting differentiated cells with inhibitors of tyrosine phosphatases and apoptosis to de-differentiate differentiated cells into lineage restricted progenitor cells.

Generation of lineage-restricted progenitor cells from differentiated cells

Methods, pharmaceutical compositions, and kits are provided for treating a subject with an effective amount of an oxytocin receptor (OXTR) agonist and an effective amount of an ALK5 antagonist. In certain aspects, the OXTR agonist may be oxytocin or an oxytocin analog (e.g., a small molecule). The ALK 5 antagonist may be a small molecule, such as 2-(3-(6-Methyl-pyridin-2-yl)-1H-pyrazol-4-yl)-1,5-naphthyridine, LY2157299, A 83-01, D 4476, GW 788388, LY 364947, Rep Sox, SB 431542, SB 505124, SB 525334, or SD 208. In certain aspects, the amounts of the OXTR agonist and ALK5 antagonist may be sufficient to induce muscle regeneration and/or neural cell regeneration in the subject.

Molecular composition for enhancing and rejuvenating maintenance and repair of mammalian tissues

Methods and compositions for somatic cell proliferation as well as increasing viability of somatic cells are provided. The compositions include heparin binding protein isolated from a medium conditioned by growth of pluripotent stem cells, such as, human embryonic stem cells, human embryonic carcinoma cells. The methods include contacting a somatic cell with a heparin binding protein composition for a sufficient period of time to provide for enhanced proliferation and/or viability of the somatic cell as compared to the absence of the heparin binding protein composition.
