Filopodia Collection

Surface of HIV infected microphage
3D representation of the surface and interior of an HIV-infected macrophage obtained using newly developed tools for 3D imaging using ion-abrasion scanning electron microscopy

Liver cancer cells, SEM
Liver cancer cells. Coloured scanning electron micrograph (SEM) of two hepatocellular carcinoma (HCC) cells, showing the numerous filopodia (hair-like) covering their surface

Migrating cell, illustration C018 / 0754
Migrating cell. Time-lapse illustration of a migrating cell, using outlines to show the previous cell boundaries. Cell migration is key to metastasis (spread) and the progression of cancer

Liver cancer cell, SEM
Liver cancer cell. Coloured scanning electron micrograph (SEM) of a hepatocellular carcinoma (HCC) cell, showing the numerous filopodia (hair-like) covering its surface

Dividing liver cancer cell, SEM
Dividing liver cancer cell. Coloured scanning electron micrograph (SEM) of a hepatocellular carcinoma (HCC) cell undergoing mitosis (nuclear division)

Dividing bone cancer cell, SEM
SEM Dividing Osteosarcoma cells Osteosarcoma is an aggressive malignant neoplasm arising from primitive transformed cells of mesenchymal origin (and thus a sarcoma)

Cancer cell, SEM C014 / 0628
Cancer cell. Coloured scanning electron micrograph (SEM) of a carcinoma cancer cell (pink) migrating (metastasising) along a layer of normal epithelial cells (purple)

Cancer cell, SEM C014 / 0627
Cancer cell. Coloured scanning electron micrograph (SEM) of a carcinoma cancer cell (yellow) migrating (metastasising) along a layer of normal epithelial cells (brown)

Bone cancer cell, SEM
Bone cancer cell. Coloured scanning electron micrograph of a fibrosarcoma (fibroblastic sarcoma) cell, showing the numerous filopodia (hair-like) covering its surface

False-colour SEM of a macrophage & lymphocyte

Filopodia, the delicate extensions of cellular life. In the intricate world of biology, these slender protrusions play a crucial role in various processes. Take a closer look at their presence on the surface of an HIV-infected microphage; they serve as gateways for viral entry, enabling this notorious pathogen to infiltrate and exploit our immune system. Zooming into another realm, we witness filopodia in action within dividing liver cancer cells captured by scanning electron microscopy (SEM). These captivating images reveal the mesmerizing dance of life and death occurring within our own bodies. As these cells divide relentlessly, filopodia emerge like ethereal tendrils reaching out into their surroundings. Intriguingly, SEM unveils a symphony of liver cancer cells adorned with filopodia. Like tiny fingers exploring their environment, these extensions enable communication between neighboring cells and facilitate movement through tissues, and are both architects and messengers in this chaotic landscape. The beauty lies not only in their appearance but also in their significance. Filopodia act as conduits for vital signals that guide cell migration during development or wound healing processes. However, when hijacked by diseases such as cancer or infections like HIV, they become accomplices to destruction. As we delve deeper into understanding filopodia's complex nature and functions, we unravel new possibilities for therapeutic interventions targeting diseases that exploit them. From unlocking secrets behind viral invasion to deciphering mechanisms driving tumor metastasis – every image captured by SEM brings us closer to unveiling the mysteries held within these delicate yet powerful extensions of life itself.
