"... has uncovered a new mechanism of the crosstalk between microtubules and actin cytoskeleton during cell division and revealed unique characteristics of the previously unexplored protein FAM110A.

"Until recently, scientists believed that actin filaments are needed only for the final step of daughter cell separation and the role of actin cytoskeleton in mitosis has long been neglected. In their latest study, the research team now demonstrates that the previously unexplored protein FAM110A has unique properties that enable it to bind actin and microtubules at opposite ends, specifically at the poles of the mitotic spindles. Microscopic analysis revealed the formation of highly dynamic actin filaments around the spindle poles which precede and guide the growth of spindle microtubules. In the absence of FAM110A, proper formation of spindle actin was disrupted, leading to severe impairment in chromosomal segregation. Accordingly, the study discloses a crucial molecular link between the two primary cytoskeletal networks during mitosis."

Comment: highly designed molecules react to each other in precise ways to accomplish the reaction of cell division. Darwinists think this evolved 'naturally'. The complexity demands a designer did it. The molecules don't think, but only react. It is a fact of biology everyone must acknowledge.
