Abstract

Defining the life span of specific human cell populations is limited by our inability to mark the exact time when cells are born in a way that can be detected over many years. In this issue of Cell, Spalding et al. (2005) describe a clever strategy for retrospectively birth dating human cells in vivo, based on their incorporation of 14C during a peak in atmospheric levels of this isotope resulting from above-ground nuclear arms testing in the 1950s.

Arlotta Lab

Dr. Arlotta is interested in understanding the molecular laws that govern the birth, differentiation and assembly of the cerebral cortex, the part of the brain that controls how we sense, move and think. She integrates developmental and evolutionary knowledge to investigate therapies for brain repair and for modeling neuropsychiatric disease.

Macklis Lab

Jeffrey Macklis investigates molecular controls and mechanisms over neuron subtype specification, development, diversity, axon guidance-circuit formation, and pathology in the cerebral cortex. His lab seeks to apply developmental controls toward brain and spinal cord regeneration and directed differentiation for in vitro mechanistic modeling using human assembloids.
