The chromosomal passenger complex (CPC) is a 'master controller' of cell division that is formed by a kinase module (Aurora B kinase) and a localization module (the scaffolding protein inner centromere protein (INCENP), survivin and borealin).

The chromosomal passenger complex (CPC): from easy rider to the godfather of mitosis
Nature Reviews Molecular Cell Biology - The chromosomal passenger complex (CPC), which is formed by inner centromere protein (INCENP), borealin, survivin and Aurora B kinase, targets to different...

Microtubule plus-ends act as physical signaling hubs to activate RhoA during cytokinesis
MT plus-end-mediated recruitment of a cortical pool of ECT2 trigger RhoA activation upon contact, which results in localized contractility during cytokinesis.
elective disruption of microtubule organization revealed that both astral and central spindle microtubules can recruit RhoA at the equatorial cortex.

Centralspindlin regulates ECT2 and RhoA accumulation at the equatorial cortex during cytokinesis - PubMed
During determination of the cell division plane, an actomyosin contractile ring is induced at the equatorial cell cortex by signals from the mitotic apparatus and contracts to cause cleavage furrow progression. Although the small GTPase RhoA is known to regulate…
It can be used to simulate forces that can be exerted at a cellular or a subcellular level
what we can have is filments and associated molecules, like molecular motors or cross linkers that interact with these filaments and exert forces even at a nanometer scale and we can see how these forces propagate over tens of micrometers
it simulates filaments based on connected segments, and you have some associated molecules which can interact with these cytoskeletal elements.

Simulating the Cytoskeleton Using Cytosim
Cytosim is an accessible simulation software – developed by EMBL scientists – to simulate realistic individual elements of the cytoskeletal network.
To position the division plane, the microtubule-rich mitotic spindle communicates with the cell cortex via Rho GTPase-mediated signal transduction pathways to locally activate the assembly and constriction of the actomyosin contractile ring at the cell equator

Active myosin-II binds to diaphanous-related formin-generated actin filaments and drives constriction of these filaments, much like the sliding filament model defining the contraction of muscle cells.
a calcium ionophore can induce calcium oscillation in oocytes and initiate the fertilization process.
