  Tkachuk and Wilson proved that a regular first countable cellular-compact
space has cardinality not exceeding the continuum. In the same paper they asked
if this result continues to hold for Hausdorff spaces. Xuan and Song considered
the same notion and asked if every cellular-compact space is weakly Lindelof.
We answer the last question for first countable spaces. As a byproduct of this
result, we present a somewhat different proof of Tkachuk and Wilson theorem,
valid for the wider class of Urysohn spaces. The result actually holds for a
class of spaces in between cellular-compact and cellular-Lindelof. We conclude
with some comments on the cardinality of a weakly linearly Lindelof space.
