Figure 5: MC-RR specifically damages neonatal EHBDs.

A) Representative images showing EHBDs isolated from P15–18 mice cultured as explants in the presence of vehicle or 400 nM MC-RR. B) Quantification showing lack of damage to EHBDs isolated from P15–18 mice pups. C) Representative image showing EHBDs isolated from P2 rat pups cultured as explants in the presence of vehicle or 400 nM MC-RR. D) Quantification showing damage to EHBDs isolated from P2 rat pups. The number of explants studied per condition is shown in parentheses. Red: KRT19, Blue: DAPI. All scale bars 50 μm.
