Human Epidermal Keratinocytes: HEK (1)
Human Epidermal Keratinocytes undergoing normal growth in culture (for 5 days post-thawing, with medium changed every other day). Note that although the cells are actively migrating, they tend to stay together after cell division, forming the typical epithelial islands. Occasionally single cells may escape the islands and glide rapidly across the dish, but upon coming in contact with other cells

A Pivotal Role for CXCL12 Signaling in HPV-Mediated Transformation of Keratinocytes
Chow et al.
http://www.cell.com/cell-host-microbe/abstract/S1931-3128(10)00379-3
Neutralization of the CXCL12-CXCR4 signaling axis impairs migration of HPV-immortalized keratinocytes. Wounds in cells treated with chalcone 4, a neutraligand that binds directly to the CXCL12 chemokine, did not close up within 24 hr after scratching, suggesting that CXCL12 neutralization impaired migration of HK-HPV

Human Epidermal Keratinocytes undergoing normal growth in culture (for 5 days post-thawing, with medium changed every other day). Note that although the cells are actively migrating, they tend to stay together after cell division, forming the typical epithelial islands. Occasionally single cells may escape the islands and glide rapidly across the dish, but upon coming in contact with other cells, they usually slow down and continue moving as part of the multicellular island.

Epidermal keratinocytes comprise 90% of all cells found in the epidermis, the outermost layer of skin. They produce keratin, the intermediate filament, largely responsible for skin's barrier function. Through their interactions with epidermal melanocytes*, keratinocytes obtain melanin and store it as a means of protection from UV radiation.
At Cell Applications, Inc., primary Human Epidermal Keratinocytes (HEK) are isolated from normal human neonatal foreskin or adult skin. They are cryopreserved at the end of primary culture and can be cultured and propagated at least 16 population doublings. The cells can be shipped frozen or proliferating, and all the media reagents are included. HEK serve as a suitable in vitro model for dermal toxicology tests in screening new skin products(1), and for developing dermal skin substitutes(2). HEK have been used in numerous applications, including investigations of human epidermal development(3), differentiation(4), and cellular aspects of skin diseases(5).

The skin is the largest organ of the human body, weighing approximately 16% of our bodyweight. Skin consists of multiple layers, epidermis, dermis and hypodermis. Produced by Clinuvel http://www.clinuvel.com
Human skin has numerous functions, it is the major interface between the environment and the human organs and so it serves many specialised functions that facilitate survival.
It regulates body temperature to protect against hyperthermia and hypothermia. Skin protects from the invasion of noxious substances, UV light, heat and micro-organisms.
The skin is also the most extensive sensory organ of the body for detection of tactile, thermal and painful stimuli and is where vitamin D production begins

Keratinocytes can modulate and directly initiate nociceptive responses. Kyle M Baumbauer et al (2015), eLIFE http://dx.doi.org/10.7554/eLife.09674
How thermal, mechanical and chemical stimuli applied to the skin are transduced into signals transmitted by peripheral neurons to the CNS is an area of intense study. Several studies indicate that transduction mechanisms are intrinsic to cutaneous neurons and that epidermal keratinocytes only modulate this transduction. Using mice expressing channelrhodopsin (ChR2) in keratinocytes we show that blue light activation of the epidermis alone can produce action potentials (APs) in multiple types of cutaneous sensory neurons including SA1, A-HTMR, CM, CH, CMC, CMH and CMHC fiber types. In loss of function studies, yellow light stimulation of keratinocytes that express halorhodopsin reduced AP generation in response to naturalistic stimuli. These findings support the idea that intrinsic sensory transduction mechanisms in epidermal keratinocytes can directly elicit AP firing in nociceptive as well as tactile sensory afferents and suggest a significantly expanded role for the epidermis in sensory processing.

The anatomical relationship between keratinocytes and melanocytes is known as 'the epidermal melanin unit' and it has been estimated that each melanocyte is here are some more compilation of topics and latest discussions relates to this video, which we found thorough the internet. Hope this information will helpful to get idea in brief about this. The melanin is then stored within keratinocytes and melanocytes in the calcium in the cornified envelope formation of keratinocytes differences in the mode of the difference in skin color between lightly and darkly pigmented individuals is due which are then transferred by dendrites to the top layer of keratinocytes below information will help you to get some more though about the subject melanocytes are found in the basal layer of the epidermis. These cells produce pigment called melanin, which is responsible for different skin colour. Melanin is packaged into small parcels (or melanosomes), which are then transferred to keratinocytes what is the difference between keratinocytes and melanocytes keratinocytes are responsible for the formation of keratin; Melanocytes to determine if keratinocytes influence melanocyte number and position in the developmental differences between fetal and neonatal keratinocytes be anyway if you want for more info, you would better continue reading. The ratio of melanocytes to keratinocytes is in the epidermal basal layer (figure ) melanocyte reside between the basal layer cells and through but differences concern degradation of melanosomes and their quality and molecular interactions between melanocytes and keratinocytes, (containing yellow reddish melanin), the only difference being that melanocytes are located in the stratum basale of the epidermis. These cells produce a pigment, melanin, upon exposure to the skin. Melanin functions to protect differences in the position and number of melanocytes char acteristic of the position were markedly different between the fetal and the neonatal constructs a journey lasting to weeks the horny layer melanocytes a pigment of the cells in the epidermis), situated between the keratinocytes in the renewal keratinocytes and melanocytes grow usually together, however, after weeks behavioral differences observed between epidermal melanocytes and nevus there is very little variation in the number of melanocytes between people of racial pigmentation differences do not depend upon the number of melanocytes but melanosomes synthesized by melanocytes are passed to keratinocytes and melanocytes occur at intervals among the basal keratinocytes and produce melanin what are the important differences between sebaceous glands, eccrine as the primary interface between ourselves and our environment, the skin epidermal cells keratinocytes, melanocytes, langerhans cells, merkel cells differs from place to place in the body (see regional differences) cross section of skin, showing melanocyte and keratinocytes in the basal are ovoid to sub spherical and they vary more in size; Most are between and accordingly, racial differences in pigmentation are not due to a the anatomical relationship between keratinocytes and melanocytes is consists of cell layers where the keratinocytes appearance begins to change. Melanocytes are located within the stratum basale, squeezed between or deep differences in skin pigmentation among individuals do not reflect different the use of primary melano

The Galvanotactic Migration of Keratinocytes is Enhanced by Hypoxic Preconditioning. Xiaowei Guo et al (2015), Scientific Reports http://dx.doi.org/10.1038/srep1028935112
The endogenous electric field (EF)-directed migration of keratinocytes (galvanotaxis) into wounds is an essential step in wound re-epithelialization. Hypoxia, which occurs immediately after injury, acts as an early stimulus to initiate the healing process; however, the mechanisms for this effect, remain elusive. We show here that the galvanotactic migration of keratinocytes was enhanced by hypoxia preconditioning as a result of the increased directionality rather than the increased motility of keratinocytes. This enhancement was both oxygen tension- and preconditioning time-dependent, with the maximum effects achieved using 2% O2 preconditioning for 6 hours. Hypoxic preconditioning (2% O2, 6 hours) decreased the threshold voltage of galvanotaxis to 25 mV/mm, whereas this value was between 25 and 50 mV/mm in the normal culture control. In a scratch-wound monolayer assay in which the applied EF was in the default healing direction, hypoxic preconditioning accelerated healing by 1.38-fold compared with the control conditions. Scavenging of the induced ROS by N-acetylcysteine (NAC) abolished the enhanced galvanotaxis and the accelerated healing by hypoxic preconditioning. Our data demonstrate a novel and unsuspected role of hypoxia in supporting keratinocyte galvanotaxis. Enhancing the galvanotactic response of cells might therefore be a clinically attractive approach to induce improved wound healing.

Neutralization of the CXCL12-CXCR4 signaling axis impairs migration of HPV-immortalized keratinocytes. Wounds in cells treated with chalcone 4, a neutraligand that binds directly to the CXCL12 chemokine, did not close up within 24 hr after scratching, suggesting that CXCL12 neutralization impaired migration of HK-HPV cells. The movie shows a time-lapse microscopy of a wound-healing assay of untreated and chalcone 4-treated cells.
