Costanzo-Garvey and colleagues studied the impact of direct neutrophil-prostate cancer interactions on prostate cancer growth. They unveiled a role of bone-resident neutrophils in inhibition of cancer growth. They also concluded that bone metastatic prostate cancer can progress via evasion of neutrophil-mediated killing. They suggest that an enhancement of neutrophil phototoxicity in bone could be a target on new bone metastatic prostate cancer therapies.
Nanolive’s 3D Cell Explorer was used in combination with Incucyte S3 live-cell Analysis for live cell imaging visualization of the apoptotic inducing role of neutrophils in prostate cancer (Figure 1).

Mesenchymal stem cells (MSCs) hold great promise for regenerative medicines such as cell therapy and tissue engineering (1,2). These approaches require cells to be grown in culture and differentiated into specific cell types such as osteoblasts (bone cells),...
Stem cells were isolated from the umbilical cord matrix and grown in culture for 14 days. At this stage most cells in the population are at the mature megakaryocyte stage and can start producing platelets in internal membranes present in their cytoplasm. In this...
