neuroblast MBp

Neuroblast that is the precursor to the Kenyon cells (Kunz et al., 2012). There are four of these per hemisphere and they each arise from a distinct neuroectodermal progenitor and produce morphologically distinct primary lineages (Kunz et al., 2012). They continue to divide from the embryonic to the late pupal stage (Lee et al., 1999; Kunz et al., 2012). All four produce largely identical lineages postembryonically (Ito et al., 2013; Yu et al., 2013), sequentially producing gamma, alpha'/beta' and alpha/beta Kenyon cells (Lee et al., 1999; Kunz et al., 2012). In the adult, each lineage remains distinct within the calyx and pedunculus, but the axons reorganize and intermingle within the lobes (Li et al., 2020).

See Ito et al. (2013) figure S1 for distinction between MBp1-4.
