A Image from a histological section of a maternally sided placental biopsy stained with Masson’s trichrome. The maternally sided biopsies comprise decidual cells (maternal origin) as well as invaded extravillous trophoblasts and trabecular chorionic villi (both of fetal origin); those biopsies are thus composed of both maternal and fetal tissues. B Evidence of carbon particles in the maternally sided biopsy of the human placenta, as analyzed in the published manuscript. White-light generation originating from the carbon particles (white and further indicated using white arrowheads) under femtosecond pulsed laser illumination (excitation 810 nm) is observed in the placental tissue (two-photon excited autofluorescence from placental and red blood cells in green and second harmonic generation from collagen in red).
