keratinocyte differentiation study 2 (KLF4 siRNA) / keratinocyte differentiation study 2

Relative Expression (log2-ratio):3.2379913
Number of Samples:2 / 2
Experimental keratinocyte differentiation study 2 (KLF4 siRNA)
KLF4 (Kruppel-like factor 4) depleted primary neonatal keratinocytes differentiated with 1.2 mM calcium for 3 days. Keratinocytes obtained from freshly isolated foreskin were grown in keratinocyte-SFM medium supplemented with epidermal growth factor and bovine pituitary extract. KLF4 depletion was done using siRNAs: KLF4i(A): CCGAGGAGTTCAACGATCT; KLF4i(B): TGACCAGGCACTACCGTAA. Differentiation was induced at 100% confluency.
Control keratinocyte differentiation study 2
Primary neonatal keratinocytes differentiated with 1.2 mM calcium for 3 days. Keratinocytes obtained from freshly isolated foreskin were grown in keratinocyte-SFM medium supplemented with epidermal growth factor and bovine pituitary extract. Differentiation was induced at 100% confluency.

oncolytic herpes simplex virus study 2 / mock infected peripheral nerve sheath tumor (S462) cell sample

Relative Expression (log2-ratio):-3.104618
Number of Samples:3 / 3
Experimental oncolytic herpes simplex virus study 2
Human malignant peripheral nerve sheath tumor (S462) cells infected with G207, an ICP34.5-deleted oncolytic herpes simplex virus (oHSV) for 6 hours.
Control mock infected peripheral nerve sheath tumor (S462) cell sample
Human malignant peripheral nerve sheath tumor (S462) cells mock infected for 6 hours.

wound healing study 2 (ex vivo; DMSO) / normal skin tissue (ex vivo)

Relative Expression (log2-ratio):-3.079895
Number of Samples:3 / 3
Experimental wound healing study 2 (ex vivo; DMSO)
Ex vivo skin samples obtained from healthy donors following reduction surgery of abdomen, and incubated in culture medium containing DMSO for 4 days. To make sure that mainly epidermis was present in the samples, as much dermal tissue as possible was removed by dissection. Skin was sliced into 1x10 mm slices and incubated in keratinocyte medium for four days with 1:1000 fold dilution of DMSO. The cultivation was performed in serum-free keratinocyte medium supplemented with transferrin, hEGF (0.15 ng/mL), 0.5 mg/mL hydrocortisone, gentamicin, amphotericin B, and epinephrine but without insulin.
Control normal skin tissue (ex vivo)
Normal skin samples obtained from healthy donors following reduction surgery of abdomen. To make sure that mainly epidermis was present in the samples, as much dermal tissue as possible was removed by dissection.
