Notch signaling is a form of cellular communication that relies upon direct contact between cells. To properly induce Notch signaling in vitro, Notch ligands must be presented to cells in an immobilized state. This protocol describes methods for in vitro stimulation of Notch signaling in mouse osteoclast precursors.

We describe a small molecule-based protocol for differentiation of mouse embryonic stem cells into oligodendrocyte precursor cells (OPCs). This protocol generates Olig2+NG2+ OPCs with high efficiency by 30 days of differentiation. We also describe a method to generate "spiking" OPCs that can fire action potentials.

FAQs
These events act as linked stages rather than isolated reactions. Cleavage and trimming reshape the newly transcribed RNA, while chemical modification marks selected nucleotides during maturation. Their coordination supports correct folding and ribosomal protein assembly, allowing the transcript to progress toward functional ribosomal subunits instead of remaining an unprocessed precursor.
Enzymes carry out catalytic steps such as cutting and trimming the precursor transcript, whereas small nucleolar ribonucleoprotein complexes help organize processing and nucleotide modification. Together, these molecular components coordinate RNA maturation with folding and ribosomal protein incorporation. Their cooperation links chemical processing to the structural assembly required for ribosome production.
Accurate processing ensures that precursor transcripts develop into rRNA components suitable for ribosomal subunit formation. Because ribosomes support messenger RNA translation, errors or disruption in this pathway can reduce the cell’s ability to produce proteins correctly. The pathway therefore connects molecular RNA maturation with cellular growth and the maintenance of protein synthesis.
Processing does not occur independently of ribosome construction. As the precursor RNA is cleaved, trimmed, modified, and folded, it is coordinated with the assembly of ribosomal proteins. This coupling helps generate organized ribosomal subunits and illustrates how cells integrate RNA chemistry, RNA structure, and protein incorporation during ribosome biogenesis.
A study can follow the precursor transcript through several connected stages: enzymatic cleavage, trimming of RNA regions, chemical modification of selected nucleotides, folding, and association with ribosomal proteins. Examining these stages together helps researchers determine whether maturation proceeds toward functional ribosomal subunits and where disruption may affect ribosome production.
Investigating precursor rRNA processing can show how cells regulate ribosome production during changing conditions, including cellular stress. It can also identify consequences of defects in the maturation pathway, such as disrupted protein synthesis. These connections make the process relevant to broader biological questions about cell growth, ribosome regulation, and disease mechanisms.
