Survival outcomes in patients with de novo metastatic Merkel cell carcinoma according to site of metastases

Frontiers in Oncology
IntroductionMerkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine malignancy of the skin with a predilection for metastases. This study investigates the clinical outcomes in patients presenting with de novo Stage IV MCC according to the ...

Swelling-activated Ca2+ channels trigger Ca2+ signals in Merkel cells.

PLoS ONE, 2008
Merkel cell-neurite complexes are highly sensitive touch receptors comprising epidermal Merkel cells and sensory afferents. Based on morphological and molecular studies, Merkel cells are proposed to be mechanosensory cells that signal afferents via ...

Bio‐Inspired Object Retrieval via Proximity‐Guided Adaptive Thigmotactic Exploration and Neuromorphic Recognition

Advanced Robotics Research, EarlyView.
Sparse active‐infrared proximity sensing is coupled to an adaptive thigmotactic controller for camera‐inaccessible object retrieval. After grasping, receptor‐informed encoding transforms force, temperature, and wrist force–torque signals into spike trains for spiking neural network recognition.

An Innervated Human Skin Equivalent that Electrically Encodes Mechanical and Thermal Stimuli

Advanced Science, EarlyView.
An innervated human skin equivalent is integrated with high‐density microelectrode arrays to reveal how engineered free nerve ending–like structures translate touch and temperature into electrical codes. Mechanical indentation and thermal stimulation engage the engineered somatosensory circuitry and evoke distinct firing and waveform signatures ...

Merkel cell carcinoma and sarcoidosis — an association like no other

Oncology in Clinical Practice
The association between Merkel cell carcinoma of unknown origin and sarcoidosis is rarely documented, pos­ing a significant challenge in distinguishing between these two conditions with drastically different prognoses.

Ileocaecal recurrence of Merkel cell carcinoma of the skin: a case report

Journal of Medical Case Reports, 2010
Introduction Merkel cell carcinoma is an uncommon skin malignancy that has a high propensity for metastatic spread. A systematic literature search identified 17 cases describing metastasis to the gastrointestinal tract, with 7 cases involving the small ...

Merkel Cell Carcinoma

Bezmiâlem Science, 2023
Merkel cell carcinoma (MCC) is a rare tumor that arises from mechanoreceptor Merkel cells. Ultraviolet exposure, immunosuppression and Merkel cell polyoma virus play a significant role in tumor pathogenesis. Although it typically presents as an initially

Human fetal skin derived merkel cells display distinctive characteristics in vitro and in bio-engineered skin substitutes in vivo

Frontiers in Bioengineering and Biotechnology, 2022
Human skin contains specialized neuroendocrine Merkel cells responsible for fine touch sensation. In the present study, we performed in-depth analysis of Merkel cells in human fetal back skin. We revealed that these Merkel cells expressed cytokeratin 20 (
